Module development and code questions

I currently have a two modules:

Module A - creates pages (nodes) with information, also generates an overview page where the nodes within Module A content type are listed

Module B - uses Module A's content to display the overview differently....with more info than a table and categorises the Module A's nodes

If Module A has a category selection, and I generate a node (using Module B) for each category; will I be able to tell the script to collect SPECIFIC CATEGORY data from Module A to be used within Module B's nodes.

What I want is a way for users to edit a new revision/copy of a published document. I need help designing just how these new revision are going to be created and entered into the database, so that they can be reviewed and published later (taking over the current revision) without messing up the system.

Still waiting for CVS approval ...

Well, I'm a total newbie to all things CVS and can't quite figure out what I'm doing. I've downloaded SmartCVS and used it to get the latest version of ecommerce/Drupal in the past, but now I'm interested in uploading a module to the contrib directory and can't figure out how. As the pages here on the site are "geared toward the Linux user," I haven't been able to get a handle on things in Windows. If anyone has used SmartCVS here or knows what it is I need to do to move my module's directory into the contrib directory with the appropriate tag, I'd love the help. Many thanks.

I am newbie to Drupal. First, I thank the Drupal developers for providing this excellent software.

Hi. I'm developing a module (an address book) and every time someone adds, edits or deletes one card I insert with watchdog a registry note with:

watchdog('Address Book', t('Edited card with name').': '.$edit['name'], WATCHDOG_NOTICE, l(t('view'), 'ck_clientes/see/'.$id));

The problem is that it adds two lines, I mean that I see two lines on the logs registry, and I guess it should be only one.

Please, any help to solve this double insertion?
