Hey Luke, Just some points that may help your UX process. I don't want to share on twitter before I know what it is. What if I find out your product is terrible (obviously I'm hoping it's not or I wouldn't have bothered signing up for an invite)? If you're going to get people to request an invite put it as the text on the signup button rather than leading on with false advertising. Chances are I won't checkout your product now that you've made me wait. I'l get an email but it will be one of tens or even hundreds and I'll skip over it as I'm in my inbox to do something else and it will soon be forgotten. Rory
