I'm not aware if it exists already
The forum should have a IRC channel for instant support
TDF have a IRC Channel, but it's not for instant support.
Though you can ask your questions there.
Server : irc.freenode.net
Channel : #krow
If you don't have any IRC Client installed you can try freenode Web IRC (qwebirc)
That's up to you. Use whatever client you like.
I just pointed you to the Server and Channel, and a webclient in case you don't have dedicated IRC client installed.
