Module development and code questions

WebFM seemed to install normally. But, when logged in as administrator, I click on "Web File Manager" and I just get a blank page.

I tried turning off all other non-essential modules, but it still will not work.

I am using firefox 1.5.

Hello,

I have like 500 pdf's that I want to put on my site for download.

The idea is to have somethink like:
Cars: ---> all the pdf about cars
planes: ---> all the pdf about planes
etc....

Is there any module in which I can make 3 or 4 categories and then upload the pdf's in them?

Maybe some kind of download module can work. Any idea?

Best Regards and thanks.

Need Torrent module? It exists for Drupal 5.0? If no can someone create it? I need it very much. I want to upload, browse and manage torrents and user statistics, ratio etc.

Any help much apreciated.
Sorry for my bad english.

I create a textarea with the following code:

  $form['body'] = array(
    '#type' => 'textarea',
    '#title' => t('Body'),
    '#required' => FALSE
  ); 

But it doesn't take html code.

And then I tried the following from api,

I have created multiple node types for a recent project, that are all pretty much dependant on one another to function as they form a heirarchy.

I've put them all in the same project as seperate modules for the installer, but if I set them up as all dependant on each other, you can never uninstall them. :)

For simplicities sake, is it possible to have multiple node types and the corresponding _hooks for each to be all within one module?

Thank you for your time.
