Remember, which i hope you haven't forgotten, Oasis Building is still here if you have building related problems....
I know its a long video but since we are talking about servers I thought I would add this to the conversation. It is a full hosting tutorial which should work on any server not just minecraft however minecraft is what I did. If you use mac you must know where your firewall is and how to navigate the system and find your computers IPV4. Also I have used PEX for 4 years now if anyone needs permission or general plugin help hit me up. Also I would recommend being a little more chill this is kind of in some ways advertising although that is not your intention.
