Add phone field to membership login

Hey! I want to require that people submit a phone number when creating a membership on my site here.

I am using BuddyPress too - any ideas?

I saw there are a few threads about this, but they seemed pretty old, so I was wondering what the latest fix for this is?


(PS - When you click "Support" is it really confusing that there is an image of the contact form that you can't actually use - nor does it directly link to the contact form).
