First of all, the active members rate is fine according to my experience..in most of the communities the average active members rate (members who post/participate) is like 100 or lil bit more per 800 to 1000+ members.
Right now our member base is very low..which is increasing and I am sure in the future as our members base grows we will see more active members.
I haven't seen any community yet where the active members rate is above 60% (infact 60% is very tight), also we can't force members to post, if they feel like posting then they will do it..else they will not! there is nothing we can do much about it..other then providing more information and interesting discussion topics.
@Desolator: What you exactly mean by GamesBasket? are you talking about something like games collection list/tacked games? kinda thing? is so then this feature is already included on the PG site, and working fine..but I haven't made it visible yet..cause I am testing it
Thanks,
