Is it possible to create custom registration forms that would use the update_user_meta function of WordPress with your Product?
I have a project where we have already created several custom registration fields using Tibulant's WordPress Custom Fields Plugin.

We're hoping to have a fully customized Registration Form, Profile Page Edit Form, and another form that would allow someone other than the actual user to enter test results to custom fields of a members profile from the front end of WordPress.
Is this possible?
