The Enderender is an XP farm designed to easily kill Endermen quickly. It was graciously built for the public, and it should be respected. The Enderender operates using redstone tripwire, and pistons. Its a somewhat expensive build, and it does get worn down with excessive amounts of people going through.
So.
We should all follow a few simple rules.
1: Don’t quit the game or tp out near the Enderender, it pauses the pistons, causing Endermen to become trapped in the top of the system, and is an annoying thing to fix.
2: Don’t break or place lots of blocks on purpose, and if you think something should be added, make it match at least. otherwise, it will likely be torn down.
3: Be careful. glass is easy to break and isn’t something many people have in their inventory a lot.
4:the Enderender is for everyone, but taking turns makes it easier to use. If someone else joins you, polity ask them to wait till your done, or let them go first.
