Post installation

I've got "mycustom.module" that contains all my hacks but is there a hook for capturing a specific CCK type's add/edit form submission?

I'd like to trigger a function to run upon each add/edit of the CCK content type.
Is is the hook nodeapi or submit... and then how do I specific the specific CCK type?

Thanks -- Matt

I run a film site using Drupal. I make each film series we run into a category, like:

Film series
- Essential Cinema
- Texas Documentary Tour
- AFS@Dobie

My question: Next to each film teaser (http://www.austinfilm.org) there's an automatically generated link to an automatically generated view of that category (or film series).

Interested in stripping the images from our outbound RSS feeds. Is there a way to do that simply? I see other tags like H2 are being removed - hoping to do the same with

Thanks

How best can I display the total number of users of a site, in say the side bar?

cheers

I have no idea how difficult or easy this would be, but here's what I'm picturing:

A webcomic node is created for Drupal, using CCK. The webcomic node has a text field called "transcription," which would be blank initially, but which would allow registered users to edit it in order to transcribe the text of an individual comic (a number of webcomics do this in order to make individual comics easier to search). Only registered users would be able to do this, and that is the only field in that node that would be editable.

My issue seems like it should be pretty straight forward, but I cant get it to work. I have some custom modules that I made (probably not well) and I would like to add the ability for users to post comments to them, but I can't get the add comment form to appear. It shoes for items such as blog or book entries, but not for custom ones. Please help! Thanks in advance.
