Hi! The password reset function seems to be out of order. The 'Send link' button doesn't send any email. All that happens is that a red 'X' appears to the left of the title.
Email is not required to create an account, to get access to password reset you need to register it on the account first http://en.lichess.org/account/email
If you don't solve the captcha it will also say Required under the puzzle.
