list of domains for university emails
philjr: If you can't get a definitive list, try a whitelist approach with a moderated queue for any domains not matching the whitelist.Once you see a domain that's an educational institute it gets whitelisted and further registrations from that domain get ok'd.No matter what text you include there, you're gonna get the odd student registering with a hotmail/gmail/yahoo account (I've tried something similar in the past). Try and get a list of free email accounts to give feedback on those straight away.I think any domain using the .edu TLD is safe straight-away, but I'm not from the US, so it may be worth clarifying that.
