Multiboxing.

The art of playing multiple accounts at the same time. For example - a cleric and a warrior-both controlled by you. Heals that land when you need them. Double the power but double the demands on your already stretched attention. This is a community of people who control two, three, four, five, even ten or more characters at the same time. The below setup is about as extreme as you can get and is not representative of the average dual boxer. Despite that, I respect their accomplishment very much - much more goes into this than what most people initially think.

Well - judging from the comments from some Diggers... not sure I want to welcome all of you. We are here doing what we enjoy doing. I can't speak for everybody but I own successful companies that are successful because of what they do and how they help other people. In my spare time, I personally play 10 accounts. I see absolutely nothing wrong with that and is about as "normal" as you can get in a world where normal ebbs and flows enough as it is.
