Instead of just having a share option for individual points (which additionally allows people to fairly easy not use the site for the intended purpose), also allow people to share this site more generally with an entire list of emails or on facebook. I'll probably just directly share this right now, but honestly didn't think about it until I wrote this up. Making things easier for people to share is always good. :)
