I just discovered this community recently and am looking forward to becoming a more active member... Up until these screenshots, I was using my laptop via VoiceBuddy and basically voice controlling my priest with a warrior.

Anyway... make sure you read the Guild Chat.... guildies started asking about how I was doing it.. and the GL asked me to repost my Damage Meters

Especially notice the first screenshot that shows a clip of my Taskmanager and just how little usage running 5 instances of WoW cost me.
