An avatar is a graphical representation of yourself. Your avatar will help people remember you and also helps keep your anonynimity and privacy.
For instructions on how to upload your avatar to your blog, checkout this great post by Sue Waters from ‘The Edublogger’.
Most important is remember to save as a jpeg file if using Edublogs.
Any age can use these avatar sites:
•The Hero Factory
•Hogwarts student – girls only *some students suggest 10+ years old
•Harry Potter and others
