There is a BABA IRC and a BABA Xat, but we dont really use either much.
A lot of people have posted threads just to find battles. A better way is to look at the BABA members list and look for people with the green lights that indicate the are online. That is what I do.
If you want to start a thread to request battles, that is OK with me. If it is inactive it will drop off of the first page of the group quickly. You can bump it if you want.
This thread worked pretty well for a while, maybe we could revive it and update it
