"Unable to display content. Adobe Flash is required." I had a small chuckle--I hope that's not the future of signup pages. Here's a description of the video, for those on their phones or flash-impaired devices: When requiring an account, have only two fields, username and password. Auto-generate both randomly and show them both in plain text. If the user changes the password, save that -- it's their new password. They can enter it on another device. Likewise, if they change the username, save that change. If they change both username and password to an existing and valid combo, consider that switching users, and I suppose you perform a logout and log in with the new credentials. (This is where it gets a little muddy, in my opinion.)
