I'm glad you like the avatar of Little Joe. If you right click on the photo and choose "Save as. . ." you can put the picture on your computer desktop so you'll be able to use it as your very own avatar. You must then go into the Settings link (top right side of any page) to put the photo you saved into your personal avatar. Just read the instructions and let me know if you need help.
Make yourself at home, find a decade group (or more) that you'd like to play an join them, so you can answer. You might want to glance at the game rules --> Game Rules but it's pretty simple, if you know the game piece, post an answer and click reply.
Lemme know if you need any help finding an avatar. I do all the answers posting and these old eyes find it easier to focus on pix rather than text to know who got the game piece right.
