Please do not close topics. Within minutes of browsing through the threads in this forum, I noticed a couple to which I would have liked adding a comment. But this is not possible because most are closed, even though the subjects they were meant to be discussed were not satisfactorily resolved.
Would it be at least possible to have a “reopen request” button or something like it?
You can flag the topic, select “Something Else”, and leave a message to the admins.
To be fair, though, if the topic has been closed for more than 14 days (which is current deadline), you’re much better off opening a new topic and linking to the old one.
