Any comments on specific survey questions that may have caused difficulty?
Pupils at our primary school found the questionnaire very easy to understand and most of them completed the questions in less than 45min.
Pretty Good Privacy
We use the Enigmail implementation of Phil Zimmerman's Pretty Good Privacy [(Gnu)PGP] in Thunderbird email for some secure communications.
Send us your public key if you want to play along. A file attached to this page explains all.
We are reassured to learn that PGP encryption software "no longer meets the definition of a non-exportable weapon", but probably not as much as Phil.
