We at Threecraft are opening the gates to new players! Threecraft is a community with several years behind it and we are planning a fresh start in connection with the release of 1.21 on June 13th. If you are looking for a server that is more or less completely vanilla, we are the server for you! The plugins we have are anti-grief and the like, so nothing that affects the gaming experience.
The server rules follow common sense. That is, don't steal, destroy anything, do anything in someone else's base without permission and ask before you use someone else's farm including villagers.
In addition to that, you are free to build wherever you want! Regardless of whether you are a builder or a redstoner, there are like-minded people on the server. We usually try to run something like Hermitcraft with a shopping district for those who are interested in that kind of thing.
If you have more questions, just get in touch!
