Why you want to be in it: I thought the idea of it seemed pretty neat, having a little group like this, so I wanted to give it a try. And not partially because I thought of what I think is a cool nickname, Psh.
Your "Mad Family Nickname": Mad Experiment (you know, cause Stitch is an experiment and my siggy and avatar are dedicated to him... Teeheehee.)
(Oh, just a heads up, it might take me a little bit to try out the chat... I can be really really really shy, like I'm feeling right now, so sometimes I need to work up the courage to do things >~<)
