I know ArcadeControls has a chat site and this isn't meant to compete or replace that by no means...
I am a moderator at a HomeTheater site and every Friday we have a chat session, it's very informal and anything from people just saying hiya and getting to know the people they see on the forums, to questions about screens, projectors, audio... well you get the idea.
Anyway I am always there Friday nights starting at 8PM, if anyone wants to drop in and say hi and talk arcades that would be great! I always like meeting new people in more of a 'real time' scenario.
Again, this isn't any type of promo or anything like that or taking away from AC's chat, it's just where I am on Fridays.
