Is there a client that does that? Sorry I lost track of the different clients. But I’d like to try. I know Eternity (which I use on my Android phone) and the default webui can’t do that. But I haven’t tried all the options.
I don’t quite get your wording. If you mean similar communities should be merged in all cases, I think I’d disagree. People might want to subscribe to a specific community. And it’d be complex to figure out moderation etc, since the root of the platform is a federated architecture and this somewhat goes against that. I think it’d be more a UI / client feature, tied into a cross-posting mechanism.
I don’t know where you live, just wanted to say if you’re dabbling in this new hobby, make sure they’re not keeping logs after your contract ends. Your IP of today might still be traceable back to you, if they keep the logs for a fixed time after the contract ended. Or use protection.
