What the best answer mark means
A best answer is the one reply on a question Wave that the asker or a moderator has marked as the reply that solved it.
How it is earned
The person who started the question Wave, or a moderator of the Flow, marks one reply as best.
- The Wave's status changes to Solved
- The person who wrote the reply gets a notification
- The mark adds 3 points to their trust score
How it is lost
A reply loses the mark in two ways.
- The asker or a moderator marks a different reply. Only one reply can be best, so marking a new one unmarks the old one
- Moderators hide or delete the reply, or its author's account is suspended (which hides their answers until an admin restores them)
One example
Fictional example. Priya asks "Can a late joiner get a partial refund?" in a cohort Flow. Three people reply. Priya marks Ravi's answer as best because it names the deadline and the steps. The Wave shows Solved, Ravi gets a notification and 3 trust points.
A month later the refund policy changes. A moderator posts an updated answer and marks it best. Ravi's reply stays in the thread as a normal reply, and the 3 points from that mark come off his score the next time it is recalculated.
