Module development and code questions

How can i tell if a node has been outlined in a book? i need to mod the print.module as it is showing duplicate "printer-friendly" urls on pages which are just outlined in a book.

However dumping $node data reveals no obvious indication to whether the node is part of an outline in a book.

I also couldn't see any function in book.module that might be able to take a node id and tell me if its outlined or not.

Is there anything out there?

Help my ignorance, - what function in Drupal allows to define term id (tid) for example at page on such URL http://drupal.org/taxonomy/term /3/9 - (tid=3)

I previously asked about permissions and the like...

Is there a set of modules already available to do the following?

- Allow students/users to post/upload files on a page
- Teacher/admin can download the files
- Files cannot be viewed by other users

If there isn't, what is the best way to go about implementing this?

I'm very new to Drupal. I want to give users basically their own web sites that they control using the Drupal system on my servers. This means enabling/disabling modules for their personal site, editing comments on content they've posted, administrating module options within their site (configuring comments for their site, etc.), allowing users to use different themes for their site only, allowing them to create their own basic themes easily and add complex themes that they've created, for use across the system or just on their site depending on specification, etc.

I'm currently using the captcha module but am concerned that I am turning people away. Would you recommend that I continue using it? What are the risks if I disable captchas during registration? How would it compromise the security of my site if ever?

Thanks in advance! :)
