How did you hear about us?
 

I want to add a field where users who are registering can tell us where they heard about the site. I already added a field, but would like to have a drop down box so I can have specific things they can choose. Then I'd like to be able to view what users selected.

Something like this is probably easy, but I'm still on pg.2 of my php/mysql book. :)

Use the dropdown custom user profile hack - with that hack you can do all sorts of things. Do a search for it. :)
