For technical questions, there is a forum under Forums->Technical Support/Web Apps Bugs->Mutual GNU/Linux , where Linux related questions (thus also Ubuntu, of course) are appropriate and best found.
For immediate contact in irc (given someone is on), there is a channel under https://webchat.freenode.net?channels=ryzomlinux . The other channels Bittty named are ok and relevant, too. You may join more than one of them using the /join <#channelname> command when connected to webchat.freenode.net or irc from an irc client.
Otherwise, Uni Chat is ok as well, and good chance to meet somebody with more or less knowledge about the topic.
