The Original Poster and Staff will now be able to mark a reply as the solution in the ‘General Discussion and Feedback’ section and the ‘Bugs and Issues’ section.
If you create a thread and someone provides an answer, here is how to mark it as a solution:
Click on the three dots next to the topic that helped you solve your issue.
Click ‘Solution’ to mark it as the solution.
It now shows up in green here:
In the original post, the solution is now pinned to the message.
What about threads themselves providing information being be a solution for someone? How can those be marked as a “solution”? Or is the new vote system and linking to said thread the only way of showing it’s effectiveness across the forum? Thanks for info 
We have introduced the vote system as a way to gauge community support for specific topics within the #self-service:bugs-issues and #self-service:wishlist categories. In these categories, you can view the most voted for items, for example, this is the current top-voted bugs list.
The solution module is enabled in #self-service:bugs-issues and #community:general-discussion-feedback and allows the moderation team and original poster to highlight a specific reply if it answers a question.
