Minecraft – Can’t choose enchantments

Pocket Edition does not even have a login system required to play the game.

The Realms Alpha login under the options menu, however, is the same as on your computer, provided you login to Minecraft on the PC with a Mojang account (login with your email address).

Villagers and villages were added in the 0.9.0 update. If you just want to create a new world with a village in it, you can use the seed 1409511342. You should spawn right next to a village. I believe every generated world will have at least one village in it. Sometimes they may be nearby, or they could be far, far away.

If, however, you want to get a village in a world you have already created, you should be able to find one after adventuring for a while UNLESS the world was created pre-0.9.0. In that case, you should be able to use MCEdit (a PC program) to copy a village from a PC world and place it in your PE world. It's pretty straightforward to use MCEdit, but if your world is 0.9.0+, you shouldn't need to use it.
