Support Forum Last Post for Closed Items

I have just updated a number of items mostly to say that they are working fine.

I wonder if support should use a “closed item” flag to show which items have no pending actions on this topic. It would then be easy to pick out the open items from the list. The current system seems to depend on support having the last word with the fix or suggestion. But really then there should be a confirmation that it has worked and most impirtant of all a thank you.
