notifying the second client computer of the existence of the comment object; and

receiving a request to forward the comment object to the second client computer.

3. The computer-implemented method of claim 1,

wherein the removing of the forwarded comment object from the queue further comprises removing any comment objects that have unique identifiers with values less than or equal to the unique identifier of the forwarded comment object.

4. The computer-implemented method of claim 3, further comprising:

transmitting the saved electronic document to the first client computer.

5. The method of claim 1, wherein the numerical identification is used to identify a location of the commented portion and the context information is used to verify the location of the commented portion identified by the numerical identification.

6. A computer-implemented method comprising:

presenting an electronic document at a first client computer;

receiving a notification from a server computer, the notification indicating that a new comment object associated with the electronic document exists;

requesting the new comment object from the server computer for automatic propagation thereto, the new comment object being associated with the electronic document concurrently accessed from a second client computer and having a data structure that includes a reference specification field containing a numeric identification that describes at least one of a beginning or an ending of a commented portion in a numerical format and containing context information that identifies at least one of the beginning or the ending of the commented portion using text from the beginning or the ending of the commented portion;

presenting a revised electronic document having the new comment object merged therein on the first client computer; and

saving, using a processor of the first client computer, the electronic document to provide a saved electronic document, the saving causing removal of the new comment object from a queue of the server computer.

7. The computer-implemented method of claim 6 wherein the saving of the electronic document at the server computer further comprises removing any comment objects that have unique identifiers with values less than or equal to a unique identifier of the new comment object.

8. The computer-implemented method of claim 7, wherein the merging of the new comment object is performed in-memory at the first client computer.

9. The computer-implemented method of claim 7, wherein saving the electronic document occurs responsive to at one of:

a manual save operation, a timed save operation, or a triggered save operation.

10. The computer-implemented method of claim 6, wherein presenting the revised electronic document comprises:

determining an action associated with the new comment object; and

presenting comment content associated with the new comment object when the action is an add operation or a modify operation.

11. The computer-implemented method of claim 6, wherein presenting the revised electronic document comprises:

determining an action associated with the new comment object; and

removing a comment from the electronic document when the action is a delete operation, the comment corresponding to the new comment object.

12. The computer-implemented method of claim 6, wherein the new comment object includes a data structure, the data structure including an action field, a unique identifier field, a reference specification field, and a comment content field.

13. A computer-implemented method comprising:

receiving a plurality of comment objects from a plurality of client computers, each client computer accessing an electronic document, and each of the plurality of comment objects being associated with the electronic document accessed from the plurality of client computers and having a data structure that includes a reference specification field containing a numeric identification that describes at least one of a beginning or an ending of a commented portion in a numerical format and containing context information that identifies at least one of the beginning or the ending of the commented portion using text from the beginning or the ending of the commented portion;

assigning unique identifiers to each one of the plurality of comment objects;

placing the comment objects in a queue according to the unique identifiers;

forwarding at least one of the plurality of comment objects to an authoring client computer for automatic propagation thereof when the authoring client computer is concurrently accessing the electronic document with at least one of the client computers;

receiving an indication that the at least one of the plurality of forwarded comment objects has been merged into the electronic document on the authoring client computer and that the electronic document has been saved thereto;

determining a highest unique identifier associated with the at least one of the plurality of forward comment objects; and

removing, using a processor of a machine, comment objects from the queue that have unique identifiers with values less than or equal to the determined highest unique identifier based on the receiving of the indication.

14. The computer-implemented method of claim 13, wherein the assigning of the unique identifiers to each one of the plurality of comment objects comprises:

assigning incrementing identifiers to each one of the plurality of comment objects.

15. A non-transitory machine-readable medium including instructions, which when executed by a machine, cause the machine to perform operations comprising:

receiving a comment object from a first client computer, the comment object associated with an electronic document accessed from the first client computer and having a data structure that includes a reference specification field containing a numeric identification that describes at least one of a beginning or an ending of a commented portion in a numerical format and containing context information that identifies at least one of the beginning or the ending of the commented portion using text from the beginning or the ending of the commented portion;

assigning the comment object a unique identifier;

placing the comment object in a queue according to the unique identifier;

notifying a second client computer of the existence of the comment object;

receiving a request to forward the comment object to the second client computer;
