First, we did the fifth server in a normal world.
Then, we created a new world to try out Expert. Unfortunately I think we were getting burnt out on Terraria by then, so you can see that not much has been done in this world, but here it is if you'd like to play with it :D
But wait, there's more! For a limited time (by which I mean, however long this website exists) you can catch up on all the worlds you've missed with the Cheerful Ghost Terraria Server Megapack! If you've missed out on previous worlds, here they are in one zip file. They have all been updated to 1.3 compatibility so there shouldn't be any issues there. It's amazing to see how far we've come.
