How do I make forum page the page that my domain goes to when i type in the url?
 

Title says all.

What directory do you have it installed in? The root or in a /forum/ directory?

well my forum path is

public_html > forums

Well, then you would use an htaccess file to redirect your url to your forums directory

See here: http://www.webweaver.nu/html-tips/web-redirection.shtml

what? I'm confused? What do I have to do?

Create an .htaccess file to redirect your url from www.yoursite.com to www.yoursite.com/forums/ and place the .htaccess file in your root directory.

how do i make an htaccess? Can you just tell me instead of giving links to tutorials about dreamweaver o.o

Create an .htaccess file and add this to it...

No but i mean how to create the base file? from what program?

Notepad, wordpad, whatever you want to use
