"community" engines and knowledge

additionally to the wide internet, community chat, repo issues, it would be interesting to allow some sort of distribution of the information on "how people use find"; which engines, cool URLs, new symbols etc.

would be nice somehow to be able to use something similar to https://github.com/internet4000/4000.network, maybe finding within "forks of Find", and get a list of custom engines shared by a user/instance/actor

It could also relate to "how Find is -customly- instanciated", for example from a `/.env.json` file served by the find instance (to feed it with initial data) etc.
