Just a little explanation: mIRC is software used for chatting IRC (Internet Relay Chat) on any of many different networks. Those networks each have their own channels, mIRC itself does have any, its a program.

There's no way for us to know which of those networks have what you are looking for, or for that matter if you mean a network or a channel. You could use a search engine like www.google.com or see if its listed on http://irc.netsplit.de/

Better than making the rounds of all the networks and doing /list *ubisoft* or /list *lobby* to get a list of channels with those words in them
