It would be very useful for the person who started a thread on the forum, to be able to mark the comment (in that thread) which solved the problem they had.
You could have the comment background show up in light-green, so that users who went searching for the correct answer didn’t have to read every comment in order to find the solution.
With that being said - I really like the forum format that Bubble uses. It’s quite a pleasure to use.
Another Idea is to have a category in the forum for discussing things not related to Bubble. It would help strengthen the Bubble community focus.
Also @emmanuel, what is the meaning behind the name “Bubble”?
