Will Forestry be staying? I'm going to be stashing everything I can carry in Forestry bags.
I'm assuming IC2 and RP2 are out?
EDIT: Luke, do you think you could bring the EnderStorage folder across to the new server? Ender Chests (the modded version) can be locked to a player by right clicking the lock with a diamond (it should go blue). If you kept the ender storage folder, we could save everything in those ender chests, boosting our storage space by... well, more than we are likely to need. Every single combination can be locked seperately. If you carry this across, nobody will lose any progress, so the reset won't hit anyone hard.
