I didn't mean piggybacking off of someone else's script, I meant code the form yourself.
A form submission really isn't too difficult.
When you have an element such as <input type='text' name='bruce'>
When it is submitted to the "Action" page (<form action='somepage.php' method='POST'>), the input will appear in the $_POST array.
So if I typed 'hello' in that input box above. $_POST['bruce'] would equal 'hello'.
The problem with the entire web design community is how people blindly throw code on their site. It can have all sorts of shortcomings, hacks, vulnerabilities, etc. However, unless you really understand it (aka, Code It Yourself), your site in vulnerable. These tools online are all great, but sooner or later, some awesome tool is going to have an exploit and thousands of people could lose their sites.
Now, I'm not saying to go code your own Forums. However, something as simple as a form can be done in very little time with limited experience.
