Is there is site wide RSS feed?

I am probably the only one here that uses RSS, but I have been trying to figure out how to get an rss feed for all new posts. I have figured out how to get it to spit out all new threads with https://www.3geez.com/forum/external.php?type=RSS2, but I won't be notified of anything passed the first post.
I use an external tool to get every post from the "New Forum Posts" panel on the homepage, but that thing is crap and half the time it doesn't even work. I would think surely there is a way to do this.
