Gaps in recommendations: How to increase participation in under-represented group?

The reader conversion group really seems to have had alot of discussion on the subject. I bet that if their discussions are summarized and the main themes crystalized, that group ain't very far from at least having identified the main problems to solve. Maybe some strategies also would turn out from such a summary. This was pretty much what I did with the Local language project Task Force when it didn't take of. Don't think I have time at the moment to do something simmilar for that group though.
