Er, Hi! My name's Ben XO and I have my own domain name. http://www.ben-xo.com/ . You're welcome.
Yes. Anyway. The reason I'm here is because I have made a useful hack for Running a Development Copy of WordPress i.e. running 2 different installations from the same database. The hack makes Wordpress work out your "home" and "siteurl" automatically - so you can run 2 copies of WordPress from the same database with ease.
I've also made a BBCode plugin (which I don't use any more because I don't like it) and a plugin which does something similar to the hack but with less pain.
