One of the easiest etiquette techniques projects can adopt is to only have the person who opened a ticket close it, in both cases where a fix was applied or it was decided not to fix.

This lets the originator of the ticket verify that the issue has been resolved or that there is no issue in the first place.

This standard practice at every sane organization and bug tracking tool. Which is not many of them, sadly.
