We have an IRC channel, connected to slack. You can join the chat using freenode web chat (#hacksoc on irc.freenode.net)
There is also the #cs-york channel, also on freenode. This is not hacksoc’s channel, but it is a great place to chat about CS stuff. Many hacksoc members also hang around there. (#cs-york on irc.freenode.net)
Our chat system of choice is slack. It’s easy to use, fully-featured and modern. But we have kept the option of using IRC by connecting our slack channel to our freenode channel.
IRC, or Internet Relay Chat, is a protocol with a long and glorious history stretching back into the mists of time. It’s a pretty simple system for online chatrooms, and you don’t even need a special program to connect to it, although they do exist.
