Username Standards on EduBuntu

[Simon Fishley]

Greetings All

I am in the process of testing my first Edubuntu server with
installation probably happening next month.  Hardware wise everything
is fantastic.  I am looking for input from the community on user
names.  My environment is going to be 20 thin clients at an
underprivileged school in a rural area. The lab is going to service
upwards of 300 children, many of whom will have the same or very
similar names so I can't just use initial and surname.  I would like
to have some way of allowing the children to keep the same username
throughout their time at the school and would be interested to hear of
other peoples naming conventions. It obviously needs to be something
simple that the children can remember.

Any comments or resource links will be greatly appreciated.

Kind regards
Simon.
