Ruby group suggestion needed

What do you mean a Ruby group? → a group like this rails group

Surely you don’t mean: http://groups.google.com/group/ruby — → this has only 256 members with low activity so it does not seem to be a good one

found this one → comp.lang.ruby (7064 members) It is from the usenet

but the activity is so high I can only get summary emails not every email like on this rails group (13913 members) but my guess this is THE Ruby group

anyone know a good Ruby group that has more than 256 members but less than 7064 ? so I could get the whole emails

thanks everyone
