Recognize Github discussions activity

[warflash]

I think it would be great to incentivize answering discussions in the GitHub discussion tab to boost activity there. Especially since the author there can actually mark specific comments as solutions.

We could consider implementing multipliers, like 3x for answering a question, and 1x or 0.5x for the author marking an answer as the solution. This would encourage people to accept answers more, since a lot of people don't do that, which can make it look like a question is still unresolved.
