Hey there Trenton/Derek, so when you look at your server via MultiCraft you should be one part that says host:s(number).hosthorde.com and one that says port: (5 random numbers).So, when you wanna change the domain, there should be two sections where you enter Host and Port. For the host, put in s(number).hosthorde.com, with the number showed replacing (number).For the port, enter those 5 numbers you see in Port on Multicraft.If you are using a site other than HostHorde's subdomain, the ip will be set up like this:s(number).hosthorde.com: (port).Hope this helped!If you need more help, let me know.
