it might be better to explain what you're trying to achieve - simply uncommenting something generally just makes things available for you to use rather than changing things automatically.

mod_rewrite is about rewriting URL's. if you've seen wikipedia's URLS, or URL's without lists of parameters after the filename, then mod_rewrite is possibly at work.

as it's generally done on a site by site basis, the best way is to create a text file in your webroot called .htaccess (notice the fullstop before the name).

as for the rest - you need to decide what you want to achieve with the URL, get a grasp of regular expressions and go from there. Here's the main doc for it: http://httpd.apache.org/docs/1.3/mod/mod_rewrite.html

assuming you've already got that far, and it's not doing anything, do you have a: RewriteEngine On in your htaccess file?

hope that helps
Cheers

Whats your rewrite rules. Post your rewrite rulese here.

You need to setup some rewrite rules in a htaccess file in order for http://domainname/john to work.

Fo example. You have a file called profile.php and you use a url parameter called user, which profile.php uses to grab the details of that user. Instead having to type http://domainname/profile.php?user=user_here
You want to use http://domainname/user_here

In order to do that a rewrite rule needs to be setup for modRewrite to use. So your rewrite rule will be something like this:
[code]# Tell Apache you want to use mod_rewrite
RewriteEngine On

# Setup the rewrite rul
RewriteRule ^([a-zA-z]+)$ profile.php?user=$1[/code]

You cannot just uncomment the mod_rewrite module and expect it to work just like that.

No. You cannot enable the mod_rewrite in a htaccess file. All Apache modules have to be enabled via the server configuration (httpd.conf) file.

Ask your host whether they can enable the mod_rewrite module. If they will not enable the module then you'll either have to find a new host, or upgrade your hosting plan to one where you can control the Apache configuration yourself (most probably  a dedicated server plan) or dont use mod_rewrite.
