Hi, Can someone tell me if the product HTML editor allows all types of HTML, if it will display forms and stuff, or are there restrictions on what you can put in there and have displayed?

I'm trying to find a work/bodge around for this: http://www.zen-cart.com/forum/showthread.php?t=109977 and thought of adding a paypal button into the description but it doesn't work. I know it's totally crazy to want to do this, but is there some setting I can override that will allow me to do this on the product listings?

And, if there is will that mean people can submit bad code into the reviews?... and, if they can, is it possible to let visitors use a different editor, tinymc for instance, that doesn't have the saftey codes overriden?
