Hi all!
I am using the built in login and register features for my website. To register, users just supply their username,password, email, security questions and answer. I want to include another field in it (Telephone number). Is there a way to do that? Please help!

Use the standard Profile Provider to add this extra information. Here's a great article on the subject by Scott.
