I have a html based site that needs a contact form. I have been doing a lot of research regarding secure forms. I have been hacked before so I am paranoid. I think "fast secure contact form" is the best option because supposedly the author has blocked pretty much all ways hackers use web forms to hack sites. but the problem is, my site's urls are all end in .html the instructions say if you want the form to work, you have to change extensions to .php I dont want to do that because of seo reasons so is there a way to get the php script to work on a site with .html extensions?
