Hey, so I own a TropiCraft server that I plan to keep up for more than a week, and it's actually modded and has bukkit! The IP is randomchimp.no-ip.org:20001 . The port is VERY IMPORTANT, as I own another server with the same no-ip. Anyway, to get the mod so you can play the server, go to tropicraft.net ! Please support them and share their mod, because they need more attention. It's a truly amazing work of art!
