After signing up and receiving the confirmation email there is a slight issue with picking a password. 1. Click the link in the email 2. The webpage opens up with a password input field and a confirm password input field in a small popup 3. After starting to type the password in the input field the popup vanishes thus not allowing me to actually save the password. Same issue when requesting a password reset (safari on mac os mavericks and on ios 7.0.3).
