Sorry for the big bump here, but what I *think* the question is, is:
"How do I have an email form on my website that sends an email to me, without using the user's email client, but still allows me to "reply" to the message and have them receive it?"
Well, it's not TOO complicated, but the short answer is:
"mailto:" will always try to open the user's email client.
What you're trying to do requires server-side scripting.
Quick run-through:
User submits form-
Server processes form and email address-
Server emails you "pretending" to be the user's email address-
-
Profit-
Basically, you need PHP or (shudder) ASP.
