@SlackAlice......I know what you mean and agree with you. It certainly is frustrating, especially in the Technology section where we both post quite regularly. Lack of feedback from a questioner leaves us Not knowing whose answer solved the problem. It's even more annoying when a number of alternative suggestions have been made and a reply does come back along the lines of... "Thanks all sorted"
I think its a good idea Lynn, as I think a thumbs down is a far better reply than a written rude insult.
Not sure if they would agree though, as they liked my idea of a reply that you last gave in a subscribed Question would come up first instead of having to search for it, but nothing happened.....good luck.
