I always find I have immense trouble finding common pitfalls like bug #41124. I have tried CC'ing myself on all those INVALID bugs that many a bug gets marked as a DUPLICATE of, but perhaps if we introduce a new Keyword like INVALID or PITFALL anyone might be able locate them more quickly. (And I could add that to the bug-wranglers guide as a simple URL[1].) [1] Well, not a particularly short URL in all likelihood, but you get my idea.
Note: I could use the whiteboard for that, but the team that any of these bugs is assigned to might have appropriated the whiteboard for other uses, whereas the Keywords field is a list and a better fit for this use.
In the spirit of the system used by launchpad.net, we could also name it ANSWER or SOLUTION. :) No, seriously.
we have Personal Tags now where you can put anything you want for yourself, but it won't be visible to others
FREQUENTDUPE A bug that is frequently getting duplicate reports Lemme know if that's good.
