https://kotlinexpertise.com/contribute-to-stackoverflow/ This one is not entirely related to Kotlin, still mentions it obviously 🙂 I know that many people don’t agree with my stated motivation, still like to share it here, feedback is very welcome K (note the new domain name 🎉)

Another good reason is to have a good Kotlin reference Q/As repository for the foreseeable future since anything posted in this slack is gone in a few days

The forum could do a fairly good job. There are some plugins for discourse that can enhanced it for that purpose.
