I'm glad to see such a great response to this thread. I have actually been able to play my first online Brawl match with a VGCharter. Woot.
I'm signing off...but I will update the OP as soon as I return. Remember everyone....if you put your code here you need to add everyone else's.
Hope to see you all online...and someone, please beat Wasumara. Just so I can see if it can be done.
