Very Simple: Add Extra Field

[slinky]

I have a forum where I'm thinking that a great way to create value added would be to have an extra field that would tell the reader a certain quality regarding their questions, for example, what country or what state they are concerned with.

I can easily place the form in the new post template:

The country you are talking about is:____

Unfortunately the name variable I'm talking about isn't being passed along with subject and message in the form to functions_newpost.php.

But from there I'm not sure of the most expeditious way to get it into the database and then pull it out again. This way there is a listing, along with the post, of all the information. I'm going to track how a new thread is stored but I'm wondering if there is an easier way. Has anyone accomplished something like this?
