Specified User Group/User Title on Registration

[Wired1]

Just throwing out some ideas to help out potential coders, the zip code profile field would have to be mandatory of course, and the hack would have to deal with non-numeric entries within that field.

What you may want to do is instead of making a hack that changes the title, you may want to have one that based upon said info, will move them to a specific user group that has the Associate title as its default.
