Neither... you simply click on "MY STATUS" and it will give you a drop down menu:
- READY FOR A GAME (Blue)
- AVAILABLE (green)
- AVAILABLE FOR FRIENDS ONLY (green)
- BUSY (red)
- HIDDEN TO EVERYONE (gray'd out)
Hope that helps.
**************
Now, if you mean your "RANK" instead of your "STATUS" the answer is scores.
Play ranked rounds, post all of your scores and when you're ready to move up in ranks, you will.
