how set pretty links in joomla ? (much like wordpress pretty links)

Visit Joomla root folder and relabel htaccess.txt to .htaccess, then visit the administration panel->site->Global Configuration

Set

Internet Search Engine Friendly Web addresses=> yes

Use Apache mod_rewrite => yes

For those who have any troubles using the new links look into the .htaccess file and hang the RewriteBase.

You have to make certain that mod_rewrite is enabled, then switch on the "Internet Search Engine Friendly Web addresses" option in Joomla's Global Configuration configurations.
