Seems to me that Tulla is entirely on topic. The topic refers to a "AA Community." There was no mention in the title about the discussion being restricted to the U.S. community.
I tend to think that, as AA is played internationally, we should learn to regard ourelves as an international community. There is a lot to be said for bringing people together and attempting to erase national differences for the sake of the game. I like to visit the UK site occasionally even if it is only to stir them up a little

Seriously, though , it is interesting to share opinions with people across the water. Becoming more cosmopolitan might benefit some of our more insular citizens.
One of the given reasons for having national communities is that it enables players to discuss things that are peculiar to their nation. Frankly I think it is more likely to cause international friction which is a bad thing for an internationally played game.
Tulla has suggested basing a central forum on the UK model with British moderators. In this regard I think he is being deliberately mischievous to get a rise out of us. Obviously an international forum should not be entirely administered by one particular nationality.
Another aspect deserving of some attention is the language difficulty. Although the majority of AA players use something resembling English to communicate some, for example the Germans, would have difficulty with this.
I think there is a lot to be said for and against an international community but it is an interesting subject and one on which I would like to see other views.
