how many players play more then 1 account at the same time.

Started out playing one on Agnarr, did two on Corinav, Mangler and until recently on Aradune. I now only play one at a time unless I need a second which isn't often. Once you can do everything you want with one, then using two just seems like a pita.

That being said I do have five accounts, all were active until recently, now I just keep two active
