De.scription and Message

I wonder if there is a guide that begginers could use to add a custom field to the user's profile. I need to add a required field called "Subdivision". The idea is that users must enter the name of the subdivision where they live so we can validate them when they request membership to a subdivision's usergroup. Don't care if the Moderator has to go and look into the profile but certainly an automated process would be great. Any help is appreciated.
