If you are unsure what IRC is then please take some time to watch the Youtube video below and there are others.
I am active on IRC (freenode) mostly either in
#dcglug – Channel for the Devon and Cornwall Linux user group
#torbaytechjam – Channel for the Torbay Tech Jam
##zleap – My own personal channel
The main advantage with hanging out on freenode, is that if you want help with a specific topic there is a chance there is a irc channel to suit. Great if you get stuck with #python, #ruby #rubyonrails, #mysql or a huge range of others. BTW I am on those channels too. I may not be able to help with everything but between the community someone can help at some point.
The chat menu link on this website goes to a web interface to Freenode which then connects to my channel ( ##zleap ), other than me, zleap you may see chanserv, other than that, it is pretty quiet (at the moment at least).
I am connected 24/7 via znc. so should see any activity the next time I open up IRC.
