I just created my Avatar. I first heard about Avatars from Jackie Siminitus at the CSLA conference last November at the Technology Committee panel. I have been curious about them since then, but haven't had a chance to try making one.
It took me a few tries to get the Avatar modifications working, possibly (altho I'm not sure) because I had pop-ups blocked. After I got it to work, it was fun looking for different hair, clothes, etc., and trying them out. As you will see in my Avatar picture on the blog, I am wearing a READ shirt. I love making READ posters, and I was inspired to get going with Week 2 today when I read Jackie Siminitus's CALIB post today about the virtual READ T-shirts. So, thank you, Jackie!
