General discussion

I see tons of Unknown table php warnings in my watchdog recently. I have no clue where they are coming from or what is causing them. Has anyone seen this before?

The request was generated from a non existing url:
/taxonomy_menu/3/1/some_pathauto_path/taxonomy/term/feedback/all/path_to_theme/style.css

An example error message:

Using Drupal 4.7.2. I enabled the "Profile" module, created some new field for users' profile (a newly created "personal information" category) .

If I enable some field in the user registration form, each field is shown correctly, user can insert his information, and it works.

But it's not possible to insert new information, or modify existing one, in the "edit" module of the "my account" menu (home >>user account>>edit). I receive no errors, Drupal answers with "The changes have been saved."... but nothing is really saved.

My commuity has been using the robust groupee forums. If I switch to drupal do I need to use a forum module or are the built-in forms robust and full featured enough for a forum savvy community?

Does drupal have a tool to build a user created directory of websites where the admin can accept or reject the post?

Is there an up to date module to intergrate with moodle? How can I search only the modules?

I want to create a large and robust open encyclopedia on a certain subject. Will I need to use a wiki module or will a Collaborative Book be enough?
