I somewhat agree with @PizzaProgram , on the disadvantage of automatically closing a subject after XX days.
Especially for those who share a flow, a node or a project.
We know there is always something to add (our women can testify 
), or a correction etc.
Why close these messages automatically?
I take an example from this topic:
Kevin was forced to open another Still testing nodes for mp4 video streaming - #4 to continue. I understand people who get lost in discussion threads.
I myself was faced with a "Share your Nodes" closed when I had bug fixes to add.
Asking a moderator to reopen, yes that's cool but not practical.
