Redirect All Non WWW To WWW?
 

What exactly do I put in my .htaccess to make it redirect my homepage AND my forums to WWW?

I have that in my public_html, but it doesn't redirect gamerzrevolution.com/forums/.

Try this:
But be sure to have mod_rewritte settings on you apache right.

It still only redirects the homepage. Do I need a second .htaccess in my /forums/ directory?

Called a permanent 301 redirect. Here's what you need:

RewriteEngine On
RewriteCond %{HTTP_HOST} ^YourSite\.com [nc]
RewriteRule (.*) http://www.YourSite.com/$1 [R=301,L]

Do I need that .htaccess in my root and my forum? I have it in my root, but it still doesn't redirect gamerzrevolution.com/forums/.

Am I understanding you correctly here? The above that I posted will redirect all non www. urls on your site to www. If you need something else, then please let me know exactly what you're trying to achieve.

I already placed that in my .htaccess, which is inside my public_html directory. My forums are located in my public_html/forums/ directory. It only redirects gamerzrevolution.com to www.gamerzrevolution.com. It does not work on gamerzrevolution.com/forums/.

Edit: I had a previous .htaccess located inside my forums directory, which was causing it to not work.

I've just browsed your forums and all threads have www. in the url. What's the problem?
