If you have been invited to at least one project/course as a Learner and also have administrative access, you can switch between the two portals by finding the Portal Toggle next to your name at the top of the page listed as "Go to". Select either the "Learner Portal" or the "Corporate Portal" (Administrative interface). Separately, Administrators have automatic access to the Trainer Portal, so this option will also be listed.
Alternatively, you may also use the following URLs to toggle between the portals:
Learner Portal: https://www.blanchardexchange.com
Corporate Portal: https://www.blanchardexchange.com/client
Trainer Portal: https://www.blanchardexchange.com/trainer
