If you want to make a MMORPG I suggest you don't make it on Minehut as you are gonna need more storage/ram. Also you'll want it to be online at all times.
I would recommend that you get a better idea of what you want to make before you get a bunch of people to help. Once you have a grasp of the idea, write it down and explain to people what is and why they should help.
Also, making a (good) MMORPG in Minecraft takes a lot more work than you probably think so fr just go play wynncraft
