Module development and code questions

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.

So I've got this rogue directory in my cvs:

I did this:

I have a custom flexinode that I have created for logging my company's phone calls. I have information like phone numbers, the date/time of the phone call, duration, client, etc. I would like to make a field for date/time that would remind that user via email at a date they specify for a "client callback". I am pretty sure this is possible since the signup module can interface with the event module and send out a reminder at a specified date. I am only hoping that I can do this with a form that asks for a date and time when the reminder email needs to be sent to the user making the report.
