Hi... All member,
I am web designer not a develper. I just create a simple html site by the help of dream weaver, css, dhtml, html, Photoshop, flash, etc.
Now I am trying to learn dynamic web site and forum. Can anyone help me on this way , what software or languages requires to learn first then second and so on.....?

The most popular pre-processing language on the web is PHP; to make a forum, you'll want to use a MySQL database to store information like users, threads, posts, etc...

Most hosts should have PHP installed, if you have one, make a .php file on your host and experiment.
Some tutorials to get you started

If you don't have a host, you can install WAMP to your PC and access pages from the web root folder (www) through http://localhost/

If you were refering to how can you create a web forum, id suggest looking into a free webhoster/free forum site, or use something such as phpbb

Google should return you plenty of stuff :)

i don't understand..
