Well, in SO I cannot access the review suggested edits, as I do not have 2k reputation. But I seem to have reviewed one in the past (which I do not remember at all).
My guess is that maybe it was a suggested edit in a post I made (a question I asked), and I accepted the edit. That is what I think from here.
A user commented:
It's possible to review a suggested edit with less than 2k rep but only if you're the "owner" of the post that the edit was suggested on
Is that true then? I have searched for the questions I have asked (quite some), and all are edited by me (typical thing you forget to format something or whatever). So I cannot seem to find anything... It is just mere curiosity.
