Contacts Importer/Simple Referral Tracking /site updates

Contacts Importer/Simple Referral Tracking --------------------------------------------------------------------------------------------------------------------------------------------------------------- I have purchased a Facebook Contacts importer as well as an email contacts importer that will send the users contacts a message inviting them to join the site. I'd like 3 fields added to registration 1)first name - this exists in table 'users' as "fname". 2)last name- this exists in table 'users' as "lname" and 3)who referred you- field doesn't yet exist in DB - users can enter either the username or email of the person who referred them. (is it possible to create a link like http://www.myslateboard.com/beta/register.register&aff=[login to view URL] ... that will auto populate the "who referred you field"? Once they successfully register the user who referred them will get 1 user referal added to their score. In the admin panel I should be able to see which user has referred the most users per month and per all time. ------------------------------------------------------------------------------------------------------------------------------------------------------------- Basic Site Updates/Fixes -I'd like the admin to have all new users be auto contacts like before the new contacts/gallery mod.
