Edit of question:
I edited the question, and then noticed that I was presented with the "your edit will be placed in a review queue" form that low-rep users are greeted with.
That's kind of confusing, considering my 27 dBRep status.
What's more confusing: I could vote on my own edit, and it now only needs another vote to be approved.
Might be related: Once in a while (every week or so), I can't post a comment. The website then shows me red box saying that unregistered users can comment, and I have to reload the page on which I want to comment to make things work.
EDIT: Happened again, this time on my own answer, a couple minutes after posting it (when I decided I want to add something to it):
cancelling and clicking edit again didn't help, reloading the page does.
