Sometimes when you read a conversation on a Structured discussion Topic, you can feel that the topic is still open, or the discussion has ended rudely. Example:
Hey, I want to know how to do [thing]. How to?
Easy: do [explanation]
If user A thanks user B, it is not visible. Some people may think the reply hasn't been seen, or user A is rude.
The idea would be to show some thanks have been given. It is also a way to show support to an idea or an opinion.
Have a link to the list of users on the number of thanks given is not possible due to privacy reasons.
