Adding fields to the aspnet_Users Table

Hey ASP,net Community,

 So I would like to store some detailed information about the Users in the authenticated users on this web application I am building and I'm trying to figure out some best practices to do this. I am using forms authentication and am using the databse that VS creates to manage users. I want to capture things like the user's phone number, business title and things of this nature. Is it ok to just add some fields to the auto-generated Users table? Is it better to add a new table and do a join with the Users table? Is there any out-of-box functionality I could be breaking by making changes to the auto-generated Users table?

 Thanks in advance for the info.
