I'd like to encourage anyone using Ubuntu to join in the community discussions using Internet Relay Chat (IRC). IRC allows group discussion in forums called channels, but one can also chat privately in 1-to-1 chat in private channels too.
There are many IRC Ubuntu channels hosted at Freenode, as a Ubuntu Kernel Team member I'm usually in channel #ubuntu-kernel under the IRC nickname of cking.
It's a great way of informally asking and answering questions - generally somebody will reply to you. Please hang around in a channel, as sometimes people cannot get back to you immediately. Please remember to be polite! :-)
For more details, check out the Ubuntu InternetRelayChat wiki page.
