Thx. Gonna do that when u get home. Can't remember my id..
[if you don't already have one set up]To set up a Battle.net ID tag, log into your Battle.net account, and look for "BATTLETAG" under Account Details (left side of the screen). There should be a link there to let you create one.
If I'm remembering it right, you can choose just about any name, and then it appends a random # to it.
*I'm just mentioning this cause I originally thought the Battletag was already set up and didn't realize I had to pick one myself.
