Module development and code questions

This is just an announcement about a set of Drupal modules being developed to serve functions specific to Access Television (public, educational and government: known as PEG) and some of the modules they will turn out will likely be of use to the greater Drupal community.

The project is called PEGspace:

I need to know if exist a module that allows navigate, find, display in a screen,drop and move file in a directory.
Of it doesn´t exist, I be glad if somebody help me with some infomation to create a module reference of this.

I want to have a flexinode type call directory listing or something with fields for website, description, etc.

I'd like to have a view of categories ala directory style where you click on a link and it takes you to the subsections and you drill down until you find something you like. I'm thinking there's already something like that with one of the taxonomy modules I've installed before but I can't remember.

Can you help me out?

Hi,

I am fairly new to Drupal and am investigating if it could serve as the basis for big multi-user blog system we are planning to build. Drupal looks great and offers a lot of functions and API's that would be useful to us.

Afaiks there are just two rather big hacks that should be made in order to fit our requirements:

I've searched for this several times, but I can't find anything relevant - although I confess its hard to dig through all of the related topics.

I have the spam module installed on my site, in order to allow me to filter trackbacks. However, despite having the checkboxes filled so that (a) it shouldn't delete anything, only unpublish it, and (b) it only should check trackbacks, and not comments, its managed to detect 2 comments as spam (which weren't) and delete them.
