Hello everyone.

I'm using JoomlaComment 4.0 beta2, on Joomla version 1..5.8, MySQL version 5.0.45, PHP Version 5.2.12

I have been searching the Joomla forum and Google, including Google's webmaster tools to try and learn how to make the url's from my blog's commenters DoFollow instead of NoFollow. I don't know if it is a change I need to make to the htaccess file, create a robots.txt file, or if it is something that can be done through JoomlaComment, or if there's a Joomla extension for this. Or if it is something completely different.
Please keep in mind, I'm using Joomla because of how user friendly it is. I'm not even close to a computer expert, so please, explain it as clearly and as simple as possible.
Any help would be greatly appreciated.
