Minecraft word 1

This is an online server my Clan and i built, It includes many buildings such as a castle,hospital, victorian style home AND THE TITANIC!!! fully built but not operational/functional yet.
I would like someone to help me make it functional, like people who know how to make fridges and pistons and stuff like that, maybe some trap door? All that cool stuff you ca play around with..

Keep in mind we will be opening for a survival server soon! I just have so much stuff to do, between downloading mods and finnishing touches..
Expeirence is a must. :) Will upload a video later today :D
Or tomorrow..
