Abstract: A system is provided for locating peers having a desired expertise. User profile information is stored in a profiles database. A search engine indexes the profiles database and appends appropriate profile tags to this information. A peer relevancy algorithm searches for candidate peers among the indexed user profile information. Weights are assigned to candidate peers based on different categories of the indexed user profile information, and peer matches are selected based on the assigned weights. In order to provide matches that are most likely to accept a connection request, data is maintained as to which potential peers have a history of accepting requests to connect and which have a history of refusing to connect. Potential matches are biased to favor those that have a tendency to accept connection requests. Contact information of requester and recipients are not disclosed until the recipient accepts the requester's connection request.

Abstract: To ensure a proper stacking order of paper tickets that exit a transaction-based printer, a stacking nip is provided which accepts a first ticket. The first ticket is fed into the stacking nip, and then advanced by the stacking nip for a fixed distance until a trailing edge of the first ticket is positioned before the stacking nip. A second ticket is then fed towards the stacking nip. The first ticket is held in the stacking nip with the trailing edge positioned before the stacking nip until a leading edge of the second ticket overlaps the trailing edge of the first ticket. The trailing edge of the first ticket and the leading edge of the second ticket are then simultaneously advanced through the stacking nip. The first ticket is ejected from the stacking nip into a ticket bin once the trailing edge is advanced through the stacking nip.
