I just started my bot @[email protected]; and it's begun subscribing to a ridiculous amount of communities. This is important because in order for a federated community to appear in the all page one member of the local instance must subscribe to that community. Some new communities I can already see are /c/UnixPorn and /c/SelfHost. Posts might take a while to populate, though, as these are new communities Hexbear hasn't yet seen
Thanks to @[email protected] for the advice in this thread.
Please note, hornyposters, that I've disabled subscribing to NSFW communities.
