We hang out in
#robustirc on RobustIRC (instructions for connecting to RobustIRC).
In addition, there are also two email mailing lists:
where announcements about the project in general and about new releases in
particular will be posted. Expected traffic is on average 1 email per week
If you are running a RobustIRC network, you should be subscribed to this list.
where anyone can start discussions about RobustIRC.
