Folks, we're trialing something new. We're uses linen.dev to index and make the entire public contents of this Slack searchable. Linen.dev displays this in a forum style format grouping conversations that are threaded. This allows folks to more easily find the amazing amount of information in this wonderful Slack community. Please let us know your thoughts. If it works out well, we'll move it to a domain under kotlinlang.org. Please note that it only indexes (and only has access to) public channels. Private channels and conversations are not accessible. Here's the link. https://www.linen.dev/s/kotlinlang
