Minecraft – I can’t add a server to Minecraft Pocket Edition v0.8.0

You can't host a server for Minecraft Pocket Edition using the PC dedicated Minecraft server. Despite the name and visual similarity, in software terms Minecraft and Minecraft PE are completely unrelated and incompatible games.

There are currently two options for hosting a PE server:

• Running an Android simulator on a PC and running Minecraft PE on that.
• Using PocketMine-MP server software.

I'm assuming you're on a multiplayer server.

To get past this, you have to type "/register", then a space, followed by any password you'll remember. Once you do that, it'll say "you have been authenticated", and you're free to (metaphorically) run naked in the rain, which is actually rather overrated. You'll have to do this again for every different server you go on that asks you to do this. When re-joining, it'll ask you to login, so you do the same kind of thing, typing "/login", a space, and the password you typed in last time. After that, you can move around and do whatever.

If this is single-player, then I have no idea what the hell is going on, and that is something for Mojang to answer.

Hope this helped.
