I am generally more a 'reader' than a contributor, as I seem to make more mistakes as each year passes! I tend to use the 'like' emoji as moral support for someone who has bothered to make a good point, although it is true, it is a very vague emoji. I often don't know what to say in response, or come to the comment long after others have intervened. What about
as a sympathetic response,
for flippant or derogatory posts, few though they are,
for obvious reasons,
or general clapping hands for when a beginner does well or one of our many sages posts a succinct comment or advice, to name a few. Does it cost the Forum more to add extra emojis? I believe that to add too many, would, as Murox, says discourage members from adding a personal comment. There, I've done it.
