I can't believe I missed posting in this when it was first, well, posted.
"werothegreat" is just a username I use for everything. It started when I played the original StarCraft, and just spammed across the keyboard, calling myself Qwertyuiop Mytrio, for no real reason. That then got shortened to Wero the Great One when I played Age of Wonders, and that got shortened to werothegreat I think when I joined BlizzForums. I think they may have had a character limit.
