I'm a doctor. I failed to use a special character in my password during signup so my domain/username got reserved but it wasn't obvious until I was informed of failure, tried again, and was told not once but twice that my username was already taken. I decided to try reseting my password, and then found two emails in my inbox, one to confirm, and one to reset my password. All on my iPad, but through the website. Very confusing. Frankly, with a full-size keyboard I can't type fast enough or click fast enough to keep up with my mouth and ears and fingers and eyes, so dictation would be awesome, but I don't see how to get that started in the iPad app. I still haven't figured out the forms...
