Thank you for posting that information. It’s embarrassing not to know those things after having been here for a while.
You're welcome. It took me a few years to figure it out.
For any "Keyword" that is attached to an FR article, you can have a list of articles (to which that "Keyword" has been added) listed in a Sidebar on your main FR page (click on a Keyword, then click on the words "Add To My Page" found on the resulting page).
That would be a way to keep up with articles you're interested in, although not all articles have the Keywords added to them (anyone can add the appropriate Keywords to an article though).
Firearms articles consistently have the Keyword "banglist" added to them by people that appreciate the Keyword feature. I have a list of them included on my main FR page :)
