I suggest creating appropriate MeeGo-related subforums at talk.maemo.org, then making talk.meego.com point to talk.maemo.org. To make a branding distinction, use two different default themes for people coming from maemo.org and meego.com domains.

PS: The existing t.m.o subforums will have to be reorganized, with historic stuff pushed down the main page, to make space for the new MeeGo subforums.
