I have changed rss.php for some specific needs of my site.
When upgrading to WP 3.3, my hacked rss.php it was replaced by the default one.
I want "my" version of the RSS generating code to "live" in my theme directory so that when I upgrade again, it will not be run over to the default.
I also want the RSS address to be as it is now so that subscribers to my feed will not have to subscribe again.
Any idea how to do that?
