theres a little more involved in that if you are planning on adding new items to your profile. theres quite a few steps, most which i cannot explain. it will involved editing your MySQL directory, a number of files in your forums includes folder, and not to mention both the profile .php files and the template files that coincide with those. anyways, blah blah blah...if you want to add new profile fields, ill get you a file that shows you how.
note: im talking about forum profile fields...not nuke
