BuddyPress.org

I have achieved something similar…

I added a report a member/contact link

which takes them to a custom page template that gathers all their information:

– username

– name

– email

etc

this information then gets placed in hidden input fields… when they submit the contact form, I get their message and all their information (they dont even know I get their name, email etc)

I am not using a wp plugin for the contact form, just some php

that is one way of doing it
