Module development and code questions

I want to develop a module.
Any suggestions on what kind?
I am a begginer.

Hello,

I'd like to add an extra tab in the "my account" page.

The module profile.module does that (it adds additional user information, and to do so adds a tab to the page).

I couldn't figure out how to do it from the source code.

In my case, I will show a custom page showing specific information about what articles the person is working on, etc.

Any ideas?

Bye,

Merc.

Hi.
I've updated flexiblock to work with drupal 4.7.
There are some enhancements:

I've created a new feature for flexinode tables. When you define a drop-down select menu, you can specify whether that menu should "filter in table". If this option is set, the table view for that flexinode type will have a filter widget above it which can be used to reduce the selection in the table accordingly. Multiple filter widgets are possible.

There is a demonstration here:

Hi , i am working on a module to provide redirection of a user on login to the page he was at or perhaps the page he was going to . Which hook should i use to set a variable holding the value of the current page?
