word. the whole getting users to register is a big problem with lots of paths. you know, you probably don't need email addresses, though. you just need people's phone numbers, right? the whole thing could be sms based, right? nothing wrong with registering online, but one could also make a register with txtful shortcut!
I like the way you think! Email becomes another way to use your shortcuts though in this case. And we need a way to communicate service or account issues that aren't a priority per se without bugging you on your phone.
