how do you post your scores

You must first have created a character on the metaverse (should be able to do so from this link). Then you have to start a new game through the 'metaverse' button on the game's main menu (not the 'new game' button!). Then just play, finish, and you'll get a prompt to submit the game.

Note that you need to be online to start a metaverse game, though you can go offline after that, save, reload, etc. When you finish, you can either go online and submit the game on the spot, or reload the "End Game Save" that it makes automatically and submit it from there later.
