firstly, everyone loves texturepacks and skins,

therefore create a couple of them, and there you have it a couple of levels after a week,
in order to keep going up levels, then keep updating it!

but to get really good, submit a mod,
but remember, mods have o be EPIC quality to be a winner.
so, make projects and blogs first.

how to make a Blog:

first, you need to think of a subject.
this subject has to be gold. for a starter do a server search, you get rewarded in two ways: cool servers and xp on planet minecraft!

To make a project:

first you need to make something cool...

...like a roller-coaster!
this roller-coaster has to be a big one. When I say big I mean BIG!

that is how to get high level on planet minecraft!

This only works until about level 15/16
