1. Click on "Profile" (top right corner, roughly)
2. Click on "Edit Profile"
3. Go down to Avatar and click on "Select a different Avatar image"
4. Select the one you want by clicking on it and then click on "Select This Avatar" (there are several pages, and they might take a little while to load - you also may have to click on "next" at the bottom right corner in order to view the successive pages ... if you can‘t see the "next" button, you might have to "maximise" the page)
5. Send me $1,000 dollars in small, unmarked bills.
