Kbin (and Lemmy) needs something to combine several magazines into one. Currently, there are many magazines spread over several instances. There's no way to just view or subscribe to them at once. You need to check them separately. If there were multi-magazines, new user could just search for someone's multi- and don't get confused by the ten other communities that often are empty.

Is there a chance that it will be ever implemented? It's one of kbin biggest blocks from getting popular.
