You should have posted in the game thread (for Art-of-war it would have been this one :
http://forum.shrapnelgames.com/showthread.php?t=43097) ...
but actually you are to late for AoW ... game is already full.
For your next game ... post a msg in the game-thread (in the shrapnel-forum mp section
http://forum.shrapnelgames.com/forumdisplay.php?f=145) with the nation you want to play. After the game is full, you should send your pretender to the adress you have mentioned.
If you don't want to wait just open your own game.
Greetings
