All Mary has to do is accept one of the email invites and create her login to Notable. Any other accounts she's been added to show up under her Accounts tab automatically when she's logged in.
Then Mary decides she wants to add users and work on her own projects. She creates her own account by clicking on her name in the upper right hand corner of the screen and following the account creation links.
Now Mary can log in with the same email address and password and collaborate on projects that Elizabeth and Beth are running, as well as run her own projects from her account called "MyFav Designs."
This makes collaboration super fast and easy! All you have to do is log in to Notable and have access to multiple projects and accounts. With an upgraded account you can refine your workflow even more by creating workspaces.
