I keep my RG account mainly for the "request full text" feature (which actually works very rarely). However, the activity over there in area of Bioinformatics seems to be as large if not larger than here. Are you an active RG user? Can you comment on their Q&A system? I had only answered once, the person who asked the question deleted my answer without any comment, so (obviously discouraged) I gave up. But I'm interested in opinions of others.
