I need to step in here.
On the one hand, you're making a "club" or whatever you want to call it, that does exactly what BP.net is here to do? If you want to be helpful, then just get out there and be helpful.
On the other hand, if you believe that your group can somehow be MORE helpful simply by being a group that works together, then maybe there is something to it.
There is no rule against such a group, although there IS a rule against soliciting monies for ANYthing without explicit permission from administrators, so that needs to stop right now.
It needs to be perfectly clear that this sort of group is not endorsed or encouraged by the BP.net administrators, but neither is it forbidden...so long as it operates within the rules/TOS of BP.net and does not become a chronic source of friction.
