Clarification on the nether:
My current plan for the nether is to keep our current starting area, and the VIP plots, plus a little bit more.
Anything outside of that area will be lost.
My advise for VIP's who have WG's and builds there; go dismantle what you wish to keep.
The newly generated 1.5 nether chunks will contain all the new goodies, plus spawners and nether forts for you to all explore, meaning you can rebuild them!
It may cause some grief for people who will lose their hard work. Any large significant builds outside the nether starting area can be saved by contacting myself in-game.
These changes will be made as soon as a stable 1.5 build is live, so get dismantling now!
It's not the ideal outcome, but it is the best overall solution for the server!
Enjoy 1.5!
