Ok, lets not whack our snakees on each others nipples now.

You need to port forward 25565, regardless of blockland.

I shouldnt have to port forward if Blockland works fine. I didnt port forward, and when Badspot made it so almost anyone can host, those people dont have any ping but the server works. my server has ping, though.
EDIT: I went to minecraft.net/download (Niven posted that above ^) and scrolled to the bottom, and downloaded Minecraft_Server.exe, and it loaded entirely. still doesnt connect.

Blockland as a thing that doesn't require you to port forward.  Minecraft doesn't.  There are no short cuts, just do it.
