It's hard sometimes to hook up with friends whose schedule is unpredictable, and whose play time is limited. In Ye Olde Days, we could check the roster every so often, or we might see they're around when a Kills Landed message scrolls by. But now, with multiple arenas, its harder to do.
Could we be allowed to enter one CPID as a "persistent find" command? That way, if they logged on the system could send a message and we could hook up what ever arena they happened to choose.
