Can I direct a User to a specific page in the community at their very first login?

There is no flag against the user indicate that they are new, but there is an open idea for this Automation: New Member Onboarding 

You could store a value in the user extended attributes to keep track of this, which would be unset the first time

Then have a custom widget widget in the footer which checked for the value and did the redirect
Then update the value in the users extended attributes in the new page/widget
