When a recommender system requires users to specify their preferences explicitly and in detail, this process can become so tedious or impractical that the system is essentially inaccessible to some users. And where the recommendation is being made to a group, inaccessbility to one or more members may preclude use by the group as a whole. The present report describes work currently in progress on a way of facilitating preference specification which is especially applicable when a group of users is communicating asynchronously. Our preference elicitation interface explicitly encourages users to help each other with the preference elicitation task and to benefit from work that has been done by other members. The basic features of this approach are illustrated with examples, and some initial user testing is summarized.
