Its been awhile since i worked on my website, life took over, but now that i got back into it--i been trying to pick up where i left off, the news system.

I was wanting to setup an rss feed button, any tips?

The system has an RSS feed built in. Options > RSS Feeds.

Create a new feed, most of the important options will be filled out for you, once created click the URL link, that'll link you directly to your new RSS feed.

Simple create a hyperlink/image that links directly to that URL.
