Dood, I think it's hard enough for most tilers to login here! lol
I'd be up for using the one you've setup, i'd idle in it, but I think when people ask in here, it helps future users and guests as they can read it for a very long time after it was talked about. Whereas in an IRC channel, you're pretty much nakard after a good 100 lines it's just too far to scroll and find the topic.
Plus, i don't think if a tilers is stuck right there and then, they will have access to the IRC channel to ask a question. there's more likely to do it when they get in, so they can ask here and wait for a reply and then go back to the job with the solution.
Dunno. Maybe it would work, maybe not.
I can make a real chat room on the forum, where we can all login and chat, but another forum I'm a member of has one and it doesnt get used much. People like asking in a forum where they can come back to in a few days and read it again sort of thing, I think anyway.
