Post installation

I´m thinking of setting up test sites/alpha versions of several websites on my localhost, perhaps as many as 20 if I want to test all my ideas in the drupal environment.

I´m going to create a database for each and run in same MySQL access, extract drupal into htdocs & rename the folder for each, and change the url in the appropriate .php file for each.

Is there anything wrong with doing it this way?
Any problems I might run into?

Hello,

Just wondering how I can properly uninstall a module. It seems that after unchecking a module in the administer section, the relevant tables still exist in the database.

Regards,

When a register user, enter his login name and password to login to my site, it gives a php error to the user

could someone tell me what the following errors mean. They suddenly appeared today on almost every page of the website. The only recent changes to the site I can think of is the audio, audio-import and spam modules were installed.

Hello all, what can I say... the forums are beating the crud out of me... with a very large stick. I have been trying to get them working for two days now and im about to go bonkers.

The problem: The forum topics cant be placed into a forum. ie. there is no category information (the listing of forum categories) for me to adjust as there should be - and yes category, taxonomy, and comment.module are installed and seem to be working. The topics are created however. They are just not associated with the forum.
