Feat: Encourage users to complete their account sign-up

[benfurber]

I think we should make it really clear where in the sign-up journey a user is.

While creating an account is the first step, it's super important that users verify their email address and complete the basic info on their profile.

Maybe something like this with a progress bar at different stages.

So what do you think @davehakkens - worth getting the illustrator to polish the illustrations?
