Maybe add another world, I know that the expanse was just created, but something that I would personally love would be a Creative Freebuild experience on the server.
 

• A teleport from spawn just like the expanse server
• Only available to a certain rank and up
• Small spawn area in a large flat world
• NO PLOTS (Please...)
• Free Build, anyone is able to build wherever they want, however big
• No griefing, as per the usual rules (maybe golden shovel? Otherwise mod enforced)
• Build competitions every few months (Not too different from the last Halloween event) 
• Redstone and Water are allowed but again, this server would only be available to the higher ranks so there would be less probability of misuse
• No worldbuilder (Wooden axe/diamond sword special commands, gotta keep it vanilla)

My final note is that I do understand completely that this would be a long term thing that would be worked on, and I do not expect an immediate response or creation. However, I just wanted to propose this idea of mine due to the lacking of good (Or any at all...) free build servers, and I feel that Wildercraft would be the perfect community to utilize this underused genre of servers.

Thank you, I hope that my message is regarded well and that consideration takes place under my request.
