I offer CoffeeMUD hosting for $14/month with first month free. Cancel before the month ends and you will be charged nothing. Go to https://pocketmud.com/HostSplash and you can get more information on our services. We provide a full community website worth over $200, and donate $5 to the CoffeeMUD developer Bo to help support the development of this MUD platform. If you decide to cancel you will be able to get a archive of your MUD. Hope to hear from you!
Right now I have a free server available, and if you want a free server, choose the "offline" payment method so you don't have to pay. When filling in your server fields be sure and put "free server" in the comments… Would love to work with you :)
