Testing, Testing, Is this thing on?

So I'm doing a little testing on the website lately. Since most of the web site is already PHP I guess there might be a chance that I might screw things up. I'm still playing with the php and mysql combination. I'm putting all my test things in the test menu so hopefully they won't cause any problems. I've currently got three different guestbooks there I'm re-coding to get to work. I haven't decided if I'm going to use any of them yet. Right now they are making my head hurt.
