Often in forums, there are certain topics that are useful to always have at the top of the listings, so that they don't get "pushed down" the list by more recent topics as they are added. It is most often seen with things like the rules and posting guidelines, but is also seen with FAQs and other basic information that is useful for people to see when they first visit a forum. (brief description [

Overuse of "sticky" topics can lead to a mess, with a ton of persistent topics that have been deemed "too important" to allow to drop, and the regular rolling topics relegated to a tiny space way down at the bottom of the screen. Good and moderate use of the "sticky" designator can be very helpful though, as it can keep people from having to ask the same things over and over again, as the relevant topics get pushed out.
In this case, a "sticky" with the master list and/or some basic information might not be a bad idea, since it would always be there at the top whenever someone clicked into the "HF Beacons" forum. I'm not entirely sure just what would be involved in designating a topic as "sticky", since I've never been in a forum moderator position, but I assume that it's just an option somewhere in the thread controls that the forum moderator can select to turn "stickiness" on and off.
