In phpMyAdmin...what's next?

Hello, as you might gather rom this message, im a totally beginner with PHP and have no experience with it. infact, it has taken me 2 days just to configure and install the thing.

now i am in front of the screen and its saying “Welcome” …all i want to do is access my guestbok and delete some of the silly things people tend to put there.

sorry, i am new here. and thankyou
