I wrote about it few days ago, but nobody responded. I registered in middle of August and from that time to today some about 20 users were registered. Half of them didn't wrote anything and from users who wrote something, only few are active. Today we have 173 users, and 100 of them didn't wrote anything – I think that we should to remove inactive, at least only those ones who didn't wrote anything.
Why they don't write? It's hard to say, maybe they register too spontaneously?
