I've been looking for a website that does that (I sometimes rent movies that I've already seen but had forgotten about). But I don't have a twitter account so I won't try yours.
Yeah, the app had to be developed during 48 hours so I thought using Twitter for login would be better for me and also for users that don't want to fill forms and stuff.
But don't worry, I'm planning to add a way for non-Twitter users access it too.
