LOL! Practice what you've already learned like building a test forum or moving one. You will be surprised to see that you will teach yourself a few things in the process.
1. Build a test forum then trash it then rebuild it.
2. Move a test forum to a different subdirectory, make sure it works properly, then move it again and make sure it works properly.
3. Practice manually installing a mod on a test forum...start with a small one with only a few edits.
4. Create an empty datbase and import another db into it then export it and do it again.
5. Go into phpmyadmin and browse a test forum's db. Play around with it and edit things. You'll soon start to see what tables hold which information.
