I recently purchased the "full" version of minecraft yet I am not sure if I am using the full version at the moment. I clicked on the Minecraft.exe (270KB) link to run the game and it works fine, also in my account it states that I am a premium member. So how do I tell if I am using the full version? What can I do with minecraft that others who havnt paid cant?

What are the pros of buying the full version of the game and how can I tell if I am using the full version? Thanks to anyone who helps me out, I appreciate it.

Is a download link going to appear here at some point?:

 Or do I use the Minecraft.exe (270KB) link which I already used??
