[OLPC-AU] Network and some further Q's

[Jonathan Nalder]

Ta guys. Sridhar has there been any cases you know of from the NT or elsewhere of kids doing much deleting etc yet? 

These are just all the questions I'll get asked re: management rights. Is there an easy (ie. busy classroom teacher easy) method to do the re-imaging then?

I'm assuming tho that with no XS backups in place, a deleted journal would be lost for good. 

Understand about the keyring - would just have to have a procedure where this was set centrally somehow initially so yes wifi passwords could be saved, but the machine was still accessible by the school tech etc.

Ta,

Jonathan Nalder
