Signing up is one flow now. You create your account and go straight into building your board, instead of being handed to a payment page before you have seen anything.
Sign up or sign in with Google on the dashboard.
The first build takes a few minutes, so that time now does something. While your board is being created you can already choose which pages your header offers, and start connecting your custom domain with the exact records to copy laid out for you.
Connecting a domain tells you where it stands, so you can see whether your records have been picked up instead of refreshing and hoping.
Invites you have not accepted yet have their own screen, so a board someone added you to is somewhere you can actually find it.
