Regarding the “first solution” badge, I feel like sometimes people don’t properly use the “solution” feature.
E.g:
Then 25 marks his post as solution even though I said what to do above (an example), therefore people will just not get badges, I don’t want people to get badges, I also don’t want people to badges when somebody “gave me the answer in dms”, a solution should be public & available for everybody to view, it’s just the right thing.
