mod_rewrite

I have a website URL www.body-builders.org and users have URLs like www.body-builders.org/user According to the virtual hosting rules I can do any configuration tweaks by .htaccess file. What I want to do is to offer my users URLs like users.body- builders.org Is it possible to do with rewrite rules in .htaccess? I tried this in my .htaccess but it doesnt help - RewriteEngine on RewriteCond %{HTTP_HOST} ^users\.body-builders\.org$ RewriteRule ^.*$ http://www.body- builders.org/users/indexr.php [L] Youri PS there are three lines in code. <>< <>< <>< <>< God is our provider ><> ><> ><> ><> http://www.body-builders.org New!!! - http://body-builders.org/index.php?links=1
