Today, I wanted to try an edit a potentially valid question which was asked in incorrect tone (as a rant) and was thus closed.
However, there was no "Edit" tag.
I know this is not a general rule on SE sites - I can edit closed questions on SO. I can also edit non-closed questions on SciFi SE.
Is this some special privilege to edit closed questions that I lack on SciFi due to insufficient rep? Or some SciFi SE specific rule?
