I found this server called The Coffee Pot SMP and it feels like someones cool home project that is finally ready for more people.

It is a Minecraft network with five different worlds. There is a main SMP world with an economy system land claiming and some quests so you can actually have stuff to work on. There is also a hardcore world if you like playing on the edge and an adventure world that uses their old realms map so it has some history.

They also have a creative world and a modded world with cobblemon but those are still whitelisted so they are more locked down.

For a few days the owner turned off the whitelist on the main stuff so new players can join and help stress test. If you like it you can ask to be put on the whitelist later. The server runs Java but it also lets Bedrock players join so more people can play together.

The whole thing feels like a small chill community that is just starting to grow and they want people who actually enjoy the game to try it out.
