You have been invited to join the Editorial Board of one of the Frontiers journals, but you cannot accept the invitation because:

1. You are already registered in Frontiers or Loop and the invitation was sent to a different email than the one you have used to create your account 
   • Should it be the case, the solution is to add the email that was used for the invitation to your account as a secondary email and, then, accept the invitation.
     
     
2. You created a Loop account while accepting the invitation, but the invitation remains pending.
   • Return to the invitation and click on the 'accept' link newly.

In case the issue persists, please contact our application support team.
