I have a room on my res, 968 on smp1, with a bunch of random spawned villagers. It's open to anyone who needs them!
i did the same thing on smp2, 4271. follow the purple wool road! (some villagers can give u enchants!)
Whenever I spawn a villager on 4004 and he has a good trade for emeralds, I announce it to everyone so they can come and get some.
