Question with form block or external form

Permalink
Hi, my problem is that i`m not sure how to make this, or how to begins, i have a website with multiple users.
When a new user make the registration i call an event and make a new public page with some of the user attributes like page attributes, the name page etc... Inside this page, a template page for all this kind of pages, i need a contact form for guest (not register users), to send the email to the user, then i need to pass dynamically the user email to the form action in the page but at the same time i need to save the message in the user profile messages( through the page id).
Can i make this if i override the form block controller or is it another way to make this?
Thanks if somebody can give me an idea.
