I'd find this useful if you sent an email every other day. The short text on the first country Namibia was interesting and about as much as I have time to read on a near-daily interest-email. I didn't sign up as I don't have the time but I'm interested to learn.

I second this as well, as a guard against forgetting about a site that I'm really excited to use :)
