izak30: From What I know (from a teacher who I sent to your site):E-mail may be super effective, but you may have more luck selling to teachers if their students don't need an e-mail address; if they can put in their (pseudo)name or 'school number' and a passcode or some such to upload to an online interface. (w/o an e-mail... w/o storing personally identifiable information of students online, etc)
