Sending a form on a custom page in vB5

[Orly]

Hello,

I've got a quick little question.

I've added a "New Page" and on that new page I'd like to have a form which users can fill out and that will be sent to my email account. The only problem I have is that I need to know the username of the user who sent me the email. So the username should be inside that email as well. Is there an "easy" way to do this?
If not, I guess they will have to fill out their username manually in the form (which I'd like to avoid).

Thank you very much in advance!
