Hey, my site is set up through google, where there seems to be little customization of pages. On my home page, I want a form and I found nothing in GoogleLabs. I've decided php isn't an option, mainly because of my ignorance and would be excited to come across a forum made of javascript. Then I can jsut copy and past it.
It is technically impossible to make a forum out of JavaScript.
Why? Simply because JS is client-side, and you cannot send any information into a database or in the server itself.
