Gmail sign in
Could we also sign in with Google, possibly? There are some Who don't have Facebook accounts, like me.

Did you ever get a response from the DreamBoard staff? I just signed up for the service and it's telling me to sign in to the mobile app to finish the registration. I think I'm about to steer clear of this app and service completely as the only way to sign up and sign in is Facebook. Known for selling its analytics and user's data to 3rd parties.
So, I downloaded the mobile app and tried to sign in through Facebook. It's giving me a Facebook API error. Obviously, the developers have abandoned this app. If they haven't abandoned it, they're slacking pretty back.
Either way, the only way being to sign up is Facebook, that is lacking. Typing this, I have talked myself into steering clear. Good luck in your bad business practice endeavors.
