This is sort of a meta-support question, but this seemed the best place to ask it. :-)
I periodically respond to support items in the issue queue. As an issue, it can and should have its status set to "fixed" when the issue has been resolved, one way or another.
Who decides when it's resolved, though? Should I set a support issue to fixed when I feel I've answered the question? Should I wait for the questioner to close it himself? Close it for him after he posts a "thanks that worked" post (which often doesn't happen)? Should a support ticket be a special case that auto-closes after X days of no activity?
Judging by the fact that magico recently went through and closed dozens, possibly over a hundred, stale issue queues, it seems that whatever should be done isn't. What should be done?
