When someone submits a bug, and it is confirmed by other members that it is a bug or probably a bug (if unsure), they should edit the end of the title of the thread to say "Bug Confirmed." That way it's easier for Zanz to see what's actually a bug and what isn't, without having to look at every thread.
If it's not a bug, then the end should also probably be changed. "No Bug" would probably suffice.
