If you use WordPress and make use of the <!-- more --> tag, some of you may want to still show the complete post in the RSS feed.

You have to change some code, but it's easy to do.

In all the wp-includes/feed-*.php files, change:

$more = 1;

To:

global $more;
$more = 1;

This will change the global more flag and include the complete post - as my blog does. Happy hacking.
