When I was just two-boxing I got alot of compliments on my prot pally/holy priest's names:

Foreground & Background


Now that I've upped to 3-boxing and added a boosted lock, who was originally slated to go into a different two-man team (never planned to maintain the 3rd account lol, now it's fully upgraded to WotLK!), so now I'm:

Foreground, Background, and Okstopdots.

I've pondered paying $10 for a name change to make the warlock "Middleground"
