Conquer-Space.net has a channel #cqs on the freenode IRC-server (irc.freenode.com:6667).
IRC is short for the protocol Internet Relay Chat. You can chat with others using it, but you need a client to connect to an IRC-server. Two common IRC-clients are XChat and mIRC.
A short tip on how to execute more than one command when connecting to a server using XChat:
First create a text file, say xchat-cmds.txt. With text file we mean a plain text file, so use a plain editor (like Wordpad or such) instead of something like Word.
The file should have exactly on command in each line and you should omit the introductory /. When you are done editing the file you save it and then enter load -e textfile as a connect command. Note that textfile has to be the full path to your command file xchat-cmds.txt.
You can register your nickname as described on http://freenode.net/faq.shtml#userregistration. Here's a short version on what to do to register the nickname <name>:
/nick <name>/msg nickserv register <your-password> <your-email>/msg nickserv set hidemail on/nick <secondary-name>/msg nickserv group
After registering you can authenticate with the command:
/msg nickserv identify <your-password>
You can join the channel #cqs with the command
/join #cqs
