Can you send me a letter giving an overview of classcraft and what it is that I can give to my administration? I would like to include it with the invoice so I can reimbursed for my purchase. I'd appreciate it if you could email me something, perhaps on a letterhead. No one here has done this before, so if it works for me, other teachers might be interested in learning about it and I could share the letter with them, too. Thank you!
