Suggestion about feature in "sin-dientes" activity

[Yader Velásquez]

Hi community.

I'm developing a game activity (in spanish Sin dientes) similar to the
hanged man, but focus
in the children context. I'm working to a foundation that deploy a
educational project in Nicaragua
with the XO. They want add a feature that allow to the teachers to
import/customize the word list.

My problem is: How to allow only the teachers to customize the list words,
and deny this feature to the regulars students?
I use the FileChooserWidget for select a file with the new list, but is not
a good idea that a child can do it.

Regards
