I've encountered a flow error on your site. I successfully registered to "pair with a developer" and listed a few languages I don't know and would love to discuss with someone. Then, I saw the option to become a pairing developer and so I tried to sign up for that, but my email address was (obviously) already taken. Should there be an option to be both, or is each role, learner and teacher, mutually exclusive on your site?
