well,

The first time i had to think on a username and didn't tought of it as much.
The admin said to me that I would most likelu get attached to the username I choosed.
Well he was right I use the username for years now:-)

Best is to think a bit about the name so it has a bit of a background you can tell. When I meet somebody I always ask where their username comes from(sometimes it tells something about them). Is it well chosen is it just a stupid thing they have chosen?

but not the fact that I am right
