I was not able to do the upgrade and preserve the avatars from the previous install. I have however, posted them all in a photo album for your retrieval.

Simply download your avatar (click on the thumbnail to get the largest version available) and then login to your account and upload your avatar.

If you have any problems, simply click on the Contact link in the side nav to send me an e-mail.
