or maybe at least the posts wouldn’t be replicated, but there would only be one community, and when you visit it, posts for the community are downloaded from your primary instance, as well as other instances based on some configuration that makes sense.
correct. so let’s have a way to “connect” communities, a way for any 2 communities on 2 different instances (or the same instance) to “merge” their content, even if they have different names (e.g. “games” “gaming”). now maybe this could be user-defined, a per client thing, like multireddits, but with a recommendation on each community page that shows the most frequent “client community-merge-configurations”
