Hi,
Take a look at the following thread. It describes how to creat your own class that inherits from an avatar:

Also, if you want to access avatars by name then you should create a dictionary instead of a list. Here is an example:
Code:
name_dict = {}
name_dict['Bob'] = viz.add('male.cfg')
name_dict['Jane'] = viz.add('female.cfg')
name_dict['Jane'].translate(0,0,3)
