Personally, I think yes. It just helps to keep things more organized, and we have been getting a good deal of them in plain GD lately. It makes since to have topics classified. That way, when a member feels like talking about gaming, they can go to GGD, knowing all the gaming topics are there. When they don't, they can come to plain GD. Not a big problem, but I think having some forced organization would make things better.
(note that this is just a suggestion for a policy change, that I know people currently can post where ever they want, and that I know Warlord, not I, runs these forums, so don't even start with that )
[damnit, I meant to have that be a poll... if any mod wants to add a poll with this topic's subject as a question, and only choices yes/no, I'd be thankful]
