I want to be able to point to a certain feed like:
I want to be able to have it formed using a different file than feed-rss.php or feed2-rss.php. Let's say I call it feed3-rss.php. The idea is that I want to use special formatting in certain circumstances (I'm going to put tracking text after the links to the each post).
This is really confusing to me, I don't seem to be able to get my head around it.
