@mrlerner and I can do this on Monday when we're running our full test. To finalize:

• [x] Home page copy and layout
• [x] FAQ copy
• [x] Terms & Conditions copoy (if we're going to have it?)
• [x] School landing page copy when there has been no contest
• [x] School landing page copy when there is a past but not current contest
• [x] School landing page copy during an active contest
• [x] Validation email copy when there is a current contest
• [x] Validation email copy when there is no contest
• [x] Post-email-validation landing page copy when a gift card was issued
• [x] Post-email-validation landing page copy when no gift card was issued
• [x] Gift card claim code email copy
• [x] Edge case copy for when student gets through validation form with a *.edu address that doesn't match the school (and we request an alternative). This is unlikely but we handle it.

Matt and I did a pass. I'm generally happy with where we landed.
