New Future For MCDen

I will have enough money saved up to get the parts for the server to order the parts Next week.
Building will begin when I have days off, and the OS for it installed and setup.
I will move a copy of the server to the new server and let players test it's setup and see how it performs. If all goes well, and hopefully better, I will lock the old server down.
When the old server is locked down, players joining it will get a notification stating we have moved to XYZ:12345

We have 24 more days until the next payment for the server. It has also racked up a couple months worth of referring. In this case, I will convert the old server, using less plugins and features, to begin a large, multiworld, adventure world system.
It's not as large or complex as it seems. There will be instances of worlds for players to play Adventure worlds. Once all the players have left that world, it will revert back to it's template and remove itself from memory.
I am looking for some adventure worlds that are SMP safe. As in two or three world folders. One normal, one nether, and/or the_end, or just one world where it all happens.
The basic plugins I think will be used is Dynmap, Pemissions, Multiverse+Portals+Adventure, and Bukkitlink.


As a teaser, a possibility for the new server, we may start up a system of individual player worlds by donation. But it will be a while before we decide on this.
