First, a problem:
I'm getting automation server can't create object for the thingy on line 80.
OK, couple suggestions:
1. Add a menu, preferably also keeping the used usernames in memory.
2. Add a normal command, no need to use /script.
Oh, and LMFAO at you using the web 2.0 logo maker.
EDIT: Screenshots look pretty cool though, but if you think "it's only a days work" and such, why not just keep writing it till it is ready? If you did all that in a day, you could have it polished up and working really nicely in 2. No need to rush a release, it'll just make people less keen to try it if they used the first version and it didn't work.
