Not sure if this is the right category but I am not sure where i should put it.
I looking for the following:
There is a page with a simple form... user puts in "username" and presses submit. They are then redirected to site.com/username
I got to the page and in the form I fill in "steve" as my username, once i press submit I am redirected to site.com/steve
Is this possible?
Yes it naturally is possible. You'll want to use the onsubmit handler of the <form> tag, and the window.location.href object to specify the new url.
