I don't see a Dislike button yet @Carol-38 ! I liked the flag feature because it was anonymous. Publicly disliking a post is really not appropriate and I personally would only use such a feature to highlight inappropriate responses in the Support Forum where a certain so-called "moderator" has not read the post they answer. I think anyone else would be too upset to have their posts disliked, so even though I did once ask for such a feature I now agree with you that it does not belong.

Yes, it's always wise to take a screenshot, or else you might believe yourself your mind had been playing tricks on you! Glad you did. It will be interesting to see if this will be a new feature or not.
