I see lots of communities with hundreds of subscribers, but no posts. What is with that? If you’re going to register a community, at least help it get going. Post some content regularly, until it becomes self-sustaining. It’s disappointing to open a community with hundreds of subscribers and not a single post.
Lurkers are fine, but they shouldn’t be making communities. If you make a community you owe it at least a post or two to not be empty
