Here’s a new version of an RSS modification for FluxBB I’m using on one of my sites. It allows the site admin to add RSS feeds from other websites. Based on SimplePie so it’s pretty flexible. Note that I did compile their code into a single file (the way it used to be when the project started) and I removed a couple of functions that were causing errors. Most functionality remains.
Hope it’s useful to others.
