Yes, most major IRC networks host a FreeBSD chat channel:
Channel #FreeBSD on EFNet is a FreeBSD forum, but do not go there for tech support or try to get folks there to help you avoid the pain of reading man pages or doing your own research. It is a chat channel, first and foremost, and topics there are just as likely to involve sex, sports or nuclear weapons as they are FreeBSD. You Have Been Warned! Available at server irc.chat.org.
Channel #FreeBSDhelp on EFNet is a channel dedicated to helping FreeBSD users. They are much more sympathetic to questions than #FreeBSD is.
Channel #FreeBSD on DALNET is available at irc.dal.net in the US and irc.eu.dal.net in Europe.
Channel #FreeBSD on UNDERNET is available at us.undernet.org in the US and eu.undernet.org in Europe. Since it is a help channel, be prepared to read the documents you are referred to.
Channel #FreeBSD on HybNet. This channel is a help channel. A list of servers can be found on the HybNet web site.
Each of these channels are distinct and are not connected to each other. Their chat styles also differ, so you may need to try each to find one suited to your chat style. As with all types of IRC traffic, if you are easily offended or cannot deal with lots of young people (and more than a few older ones) doing the verbal equivalent of jello wrestling, do not even bother with it.
