ArchitectMCVote and grow the world
In game, type /vote. There are four sites. Each vote pays 2 diamonds, 8 XP bottles, 8 quartz, and 4 sea lanterns, and pushes the world border out a little.
Vote all four in the same day for a bonus: 4 diamonds and 16 waxed copper.
Why it matters
The overworld, nether, and end all grow when people vote. More votes means more land for new bases. It is the nicest thing a new player can do on day one.
