There is a set of basic tutorials at www.BoonexNerd.com for questions such as these.

The tutorial is titles "How to Change the Footer" and is part of a series of tutorials I wrote a few months ago. You can find more at the site.

I've been writing a custom profile tutorial that I hope I can push out this month. That one is long overdue.
