I'm already familiar with how to use onSubmit to evaluate form content against RegEx to ensure it meets static parameters for acceptable content.  What I'm wondering is if there is a way to further provide validation against a MySQL database, such as if you want to make sure an e-mail address hasn't been used yet before submitting a form and having to re-load the field data back into the proper places for correction.
