From: Broughton, Northants, UK
My name is Martin. I use Mart because when I sign up for a board, Martin is usually already taken. For some odd reason, I use mart on some boards, maybe as Mart was taken. When I first started going on forums, and got panicked by not being able to use my real name during the process of signing up, I used the name of my favourite pet, "Bassett", but I hated using a pseudonym so much that I soon managed to persuade most administrators to just let me revert to Mart or mart.
At the risk of being controversial, I have just never seen the point of using pseudonyms. They can often give you the wrong impression of someone, before you even have a chance to get to know their views. On the other hand, the combination of someone's username, their avatar, and their signature can often warn you that you are about to have an exchange with a psychopath.
Martin is the name my parents gave me. I haven't always liked my name, but it's the only one I've got. I did have nicknames at school. Although they were always fond, they were often also racist, and I never "took them with me" when I left anywhere.
