A few weeks ago Grzesiekk started the #powercli Internet Relay Chat channel at freenode.net. At this moment the channel has around five users. And we use it to chat about PowerShell and PowerCLI related things and to hangout. It is not intended to replace this forum. Everybody is welcome to join the #powercli channel.
If you do not know how to connect to IRC using an IRC client (x-chat,mirc,irssi,etc…) you can join the freenode webchat client at: http://webchat.freenode.net/
