Hi all, my name is mark.

[Arctirus]

Hi Arctrius, Nice to meet you. I really think Mark is a great name.
Whats you're little trademark all about? Because of you're screen name I think of cactus, but when I look closer it looks like a hand caught some gears. Anyway I like it.
Mark.

The names is a derivative of Arcturus, a star and yes, it is a hand in gears. It's an industrial safety placard.
