making a forum in website ??????

Well, you can easily and freely set up your new forum in 10 minutes. Let me give you a little explanation. If you already have a website then we passed 75% of the process. From your Cpanel, Just make a new folder and name it "forum" as an example. So that will be the folder which contain all your new forum files. Visit simplemachines.org where they are offering a free forum package script with an install file to make it easy for you to setup your forum. Download that package freely then upload it again on the new folder you made on your Cpanel. Once finished uploading just run the wizard by running install.php on your browser. Its a wizard which helps you set the forum options fast before starting. Once finished that wizard, then you are done. Hope that helps. Good Luck ;)

Dudz it is not possible with html and javascript. You have to use php and mySQL for that.

You see html, javascript, css etc are not server side languages. They just work on your computer(clients) But when you pst something in a forum it is stored in databases And when someone checks your site that content is included in the page sent to the clients computer.
