Well, I have a suggestion...
The members could all agree (unless SimHQ wants to enforce it) that for a set amount of time (say...3 months?) that there'll be no OT, only discussions related to gaming and simming. Just see where it goes, it doesn't *have* to be a permanent condition. The site will either become more active (and I think some believe that it will) or less active, in which case the OT stuff can be allowed to continue.
Weird idea coming from me, I know. But I'd respect it (assuming I'd have the choice).
I want the credit if this idea takes off.
EDIT: Anything military should still be allowed, as most sims are military related.
