Except half the time nothing really happens on IRC. Takes too long sometimes to get an answer. By that time I just get bored. Seems easier to be able to just chat with them on xFire or something, where you know they're going to answer in the next few minutes.
I personally find #pbmappers somewhat pointless. Seems way too, for lack of a better word, formal. Something you'd probably go on just to get help or something.
Anyways, a lot of the idlers on the channel are top mappers like DT or you guys, and some of you'd probably be less willing to do a little mapping with new guys which I wouldn't mind doing, as it gives me practice.
To answer Chef-Killer, I meant a team that gets together occasionally and makes maps for fun, even if they're not going to be released. Helps us more amateurish mappers to practice more while pooling ideas.
As I've clearly stated as well, this team is nothing serious. You could call it a bunch of friends getting together and brainstorming ideas and possibly making good ones work. If there are any.
