They provide a bag of goodies that he used at our table and it was useful for his work when he went to Haiti with Waveplace. I think they might be someone to ask about either providing a kits or ...... helping certain small groups as part of 'good will', 'tech outreach' with a 'shout-out' to them or such. They run a 'free day' which I have been party to, and they are generous with their efforts at creating a community of Makers. We might be able to work with them on kits or be a recipient of their outreach. -Kev _______________________________________________ IAEP -- It's An Education Project (not a laptop project!)
