I don't like your access for 3 signups model, though. Since I have no idea what it is or who you are (other than my intuition that you're a nice guy), you're asking me to bet my standing with 3 others - and more importantly, their contact details - for an opportunity of unknown value at some unknown point in the future. Perhaps it will be awesome, perhaps I'll be splashed all over pathetic-wannabe.com. This is a risk I don't mind taking with my own email address, but which I'm unwilling to subject others to.
