Sending a form on a custom page in vB5

[Orly]

Thank you! I tried it out. The PHP code works perfectly in a php-module.

Unfortunately, the email form I created is HTML + Java and if I add this code to a php-module, it doesn't work properly.
Is there a way to display the user's username in an email sent via a email form in a module?

Sorry, I know my way around HTML, but PHP is still a little new to me.
