1. An Avatar is a virtual "person" that you can create and personalize online.
2. Someone might use an Avatar to use if they are a teacher, or some sort of Graphic Designer, or even just for fun toput on a personal blog.
3. No...
4. Of the 3 Avatar websites I like Voki the best it seems easiest to use and the most fun because it lets you have a voice and there is fun settings.
