We use Yahoo IM conference feature.  Yahoo IM is a free download if you don't have it yet.  Then send a friend request to iowamarf (me).  I usually open, and post beside my name that chat is open.  If I can see you online and know you want an invite I try to automaticly send invite, if you don't get one and want to join us just IM me.  We are usually there Sun, Wed, and Fri from 8 eastern until everyone gets tired or has left!  If other times are needed we often can find people available to lend support.
