I am a designer and have never done the back-end of a form before.
How do I activate a form? I have made a practice form in Dreamweaver and saved the page as ASP. How do I make the submit button send the content of the form to an email address using Dreamweaver?

Anything else I should know?

Please help.

You can use Email Components like
ASPMail, ASPEmail or JMail

Read Example of Simple ASP E-mail Form

Also you can use BrainJar's ASP Formmail

You can simply use the CDOSYS or CDONTS components that come with Windows (dependsing on which version you have - CDONTS for WinNT, and CDOSYS for Win2K or Win2K3 Server) however I have seen some hosts disable these and only let you use things like JMail. Talk to your host, network admin or whatever and find out whats available. Once you know which component to use, search Google for example scripts. I'd stay away from things like ASP Formmail - they're just bloatware.
