1. A computer implemented method of recommending items to a current user, comprising the steps of:

  • creating a master list of items from which a plurality of users may select;

    accepting from the current user an input list of items which the user enjoys;

    storing said input list;

    generating all combinations of pairs of items in said input list, and identifying each of said pairs as a link between two items from said master list, wherein each link includes a first part corresponding to a first item and a second part corresponding to a second item;

    storing in a LINKS table each generated link, wherein duplicate links generated by more than one user are represented by a weighting number stored in association with the link;

    identifying all items in the input list that exist as the first part of a link in the LINKS table;

    identifying for each of the identified items in the input list, the corresponding second part of the link in the LINKS table as a result item;

    generating, for each of the identified items in the input list, a result weight based on the weighting number associated with said link associated with the identified item;

    generating a RESULTS table, said RESULTS table containing a list of all the result items and respective result weights; and

    presenting said result items contained in the RESULTS table to the current user.
