Is there a way to make a form that the person would put their email address and for example, a question in and then that gets mailed to my email address (I can do all this so far) and in the email that email address the submitter entered would be considered the return address?

if you are using a serverside language such as Perl or PHP, yes, that is possible.

if you are using a mailto in your action value, probably not. this version would also have problems with some visitors.

if you are using a third party processing software (such as bravenet) you will have to check out the settings within your account login.

How would I pull it off then? I have my own domain and I have php and tons of other stuff.

a lot of people use that one...but theres many others too, just chose the language you want to use (like php) then search google for 'PHP form mail script' or something similar :)
