Alright, so I'm a member of both Forgehub and Halopedia. I just saw on the front page that Halopedia is an affiliate of Forgehub, and it seems like Forgehub regularly hosts tournaments in Halo 3. Halopedia also hosts a tournament, albeit only a semi-casual internal one, called Halopedia Warz. I was wondering if anyone here would be interested in having a friendly competition between Forgehub and Halopedia. I don't know who would arrange it or how/when, I'm just putting the idea out there. (I'm also announcing the idea on Halopedia. It'd have to be approved by the admins, too.)
Heh, now I have to get in contact with the admins. They're kind of slow to respond, being busy with the wiki and all... I'll post here as soon as one of them says something.
