Module development and code questions

I created a node type module and write a form for it. Can I remove or just hide the default form part which are called 'Menu settings', 'Comment settings', 'Authoring information' and 'Publishing options'?

What would be the best way to categorize incoming email (via the mailhandler module) with the appropriate taxonomy based on the subject line? I'm going to be recieving emails with a subject line format [List Name] : [Category] : [Post Title].

I would like drupal to automatically put the newly created node into the [Category] taxonomy and rename the node title to just [Post Title].

Any ideas on how to best approach this issue? I'm thinking of creating a custom node type which does the modifications and taxonomy changes within the insert hook.

The mailhandler commands aren't capable of handling anything of this level of complexity, are they?

A phptemplate modification could probably address modification of the title to remove the [List Name] : [Category] : bit, but I don't know of a simple way to categorize the module based on title.

Using the CCK module seems like another interesting approach, where the computed field module could be used to check if the title has been fixed yet (from [List Name] : [Category] : [Post Title] to just [Post Title], and if not then do the taxonomy addition and rename the module.

Anyone using the UIE Forum yet?

Had a couple of quick questions for you about it if you have. Do posts made on the original drupal forum transfer over to the new forum; AND have you had any trouble installing or using the forums.

Thanks,
Nick

I was wondering how to integrate already existing data in the selection list of user registration and profile. For example, when a user signs up he would have to choose a value from a drop down list that are values which other users entered when they signed up, or, if the value is not there that the new user can add some value to that developing selection list.

Can someone help me load info dynamically or refer me to good thread.

Problem: I'm using OG Vocab. if a person wants to post to multiple groups, they Simply click the checkboxes next to the groups they can post to. Great! but I want the page to automagically include the new vocabularies for all the selected groups When the groups are clicked.

Right now they have to do a post preview to see available vocabs. this is too disruptive.

I am looking for some kind of code where there would be a link at the bottom of a page post. i.e. similar to "E-mail this page".

What I would like to happen is a textarea box with the content of the page to be populated just below the post. with a secondary button that would copy the text of that textarea box in to the users clipboard to copy into another page, i.e. myspace.
