If only they knew what a lot of what they use runs on... :) I'm glad you're thinking of getting involved in SDF, Tom. I'm trying to expand UKTeam's Ubuntu wiki pages.  Perhaps you could add a bit about what you're trying to do with GIMP and SDF on <a href="https://wiki.ubuntu.com/UKTeam/Education">https://wiki.ubuntu.com/UKTeam/Education</a>?  It'd be interesting to see your thoughts on the easy of Edubuntu trials in public vs state schools on there too.  If you're not really wiki-inclined so-to-speak, I could add  a bit in about your school from what you've said in this conversation?  Up to you tho!
