I can write my filters here, but I think that I've lost it all, ah another thing, in the latest version the communities kind 10004 was empty too. I see that the amethyst prefer to add the communities in the kind 3 than 10004. I think that the kind 10004 is for joined and the 3 is for following, what do you think about that?

Ah, I'm working in the @Norkut client and I use the kind 10004 to list the joined communities...

Encrypted communities are the best approach to follow now? What's your vision about the public communities? I think it could be good to see what are the communities of an user.

Then we could consider the communities in the tags could be the public ones.

Yes, the communities that are in the tags are public, the ones encrypted in the .content are private follows.
