Let's say you made a town and want to show it off, maybe even have a warp set there, you can make a post that looks something like the following:
Hey guys! I made this EPIC town! I feel like the community would like to build around it, or maybe even live with me and my friends so could there pls pls pls be a /setwarp there? The coordinates are [insert x,y,z] and it was made by [insert username]
(P.S This is the best town I've ever made)
Thanks so much! Much love...
Now THAT is a great post. The coordinates are very important if you want a warp to be set there.
