Funny because I thought they were one of the best features of any forum I have visited.
They would be if we could make some sense out of them.
How does it determine which ones to display?
I see some about discussions that I have participated in, and others that I haven't.
I see some for discussions in the new forum, and some in the old forum (which I thought was closed?)
Dozens of them appear at times, and none at other times.
I can't tell why sometimes and not others?
Once you click on one, they all go away, only to re-appear in some other combination at a random time.
They are not predictable enough to be useful, IME.
It is currently buggy but I think it is from the team moving topics over.
