The rub is that we are also an association of privacy professionals. This means our members care deeply about where their personal data ends up. Unfortunately you have no privacy policy on the site which prevents me from even suggesting it to our Membership group -- it would be summarily dismissed without consideration.
It's a common mistake among MVP sites to overlook this detail but often a generic privacy policy would likely be enough for most and shouldn't take more than a couple of hours to put together. I think it would be effort well spent.
