Welcome to the wonderful world of NineBlock!
During your stay, do your best to carry out these tasks:

1. Craft a bed. (Spawning on NineBlock may be tricky without it, so make this your top priority.)
2. Make an infinite water source.
3. Build a snowman.
4. Turn the nine blocks into one island.
5. Enchant a diamond pickaxe.
6. Build a functioning nether portal.
7. Craft a flower pot and put a flower in it.
8. Craft a TNT block.
9. Last, but not least: Have fun!

EDIT: The first version had no way to complete the seventh task, so I've updated and added snow and pumpkins to the mix. Enjoy!
