I just made !nsfw411@lemmynsfw.com with the intention of using it as an organized catalog of communities, categorizing them by type. Feel free to post any communities and the categories they may fall under. The communities also don’t have to be specifically on lemmynsfw.com, they could also be from other lemmy instances or maybe kbin instances.
If anyone wants to help with the categorizing, message me or reply.
Love to help, no idea how. Very new to this and not sure how to find anything. If you can train me on that, I’ll spend time searching and logging stuff in the list.
