Putting this on hold. The original plan was to push all new users to Lemmy.world, because it has open sign ups. At the moment, many PieFed instances have open sign-ups. I'd rather push users to those PieFed instances to avoid centralizing everyone on Lemmy.world, but we need PieFed to implement API support for that first.
