Hello,   I'm currently working on a server with some friends, blabla.   We've got a loadshit of ideas we're working on right now, but this one is blocking us. What is really needed to create a Multi-Block Structure ? I mean, I looked on the Nether Portal code, but still, it's almost incomprehensible.   If you could send me the steps for that, but don't give me the code please it won't really help me.   Regards,
