I think a “Thank You” button would be a good replacement for Informative. I feel like it would not be abused as much, and could mostly serve the same purpose when used properly. Most people would not want to thank someone for a post they don’t like or agree with. My thoughts on Disagree/Dislike, if you can’t handle them, you are too young and immature to be on the forum. They could be useful when used properly.
