http://maemo.org, not talk.maemo.org

maemo.org accounts are also linked to garage and wiki so if you have a garage or wiki account you should be good to go.

Also I have to repeat here the fact that you have to link your tmo and maemo.org accounts for karma to be calculated against your posts/thanks. Thus, if you want to vote, you're below the 10 karma threshold and haven't already linked do it now, as it takes a few days for karma to be updated.
