Yeah I think it should be left up to the OP. If mods want to make mention, but I think the OP should have final say. I mean, me and nnodley are off topic for now, but will be on topic once nnodley starts updating.
I agree. I mean, if it becomes obvious that a decent thread could be made about the off topic discussion going on then I would just step in and say, "Hey guys, let us know if you're going to discuss this further and we'll just turn it into a new thread for you". Instead of going, "Hey! Shut up and get back on topic. Go make a new thread and repeat everything you just said if you're gonna keep it up! You've been warned!".
