Can't help with Xmas avatar, hope this helps.
Gravatar is the service that The AnswerBank uses to display avatar images across the site. You need to sign up to Gravatar (found here
http://en.gravatar.com/site/signup/) with the SAME email address that you signed up to The AnswerBank with and have just found from your profile page.
Using the “My Account” tab on Gravatar, scroll down and click on “Manage Gravatars”. From here you can upload any image saved on your computer and use it as an avatar. The image can be of anything (within reason, of course!) and allows you to add a personal touch to your AnswerBank profile.
Step 3: Activate your Avatar
Once you have signed up to Gravatar visit this page
http://www.theanswerbank.co.uk/user/stats.php and click “Activate Avatar” in the top right corner of your profile. This will allow The AnswerBank to make the connection to the Gravatar service and start to display your avatar image.
