When you create a review you will be prompted to add others to your review.
You can also invite reviewers to your review at any stage in your review by navigating to the Settings screen from the review dashboard, and clicking on the Add/Remove reviewers link.
Covidence will send an automatic invitation email to the invited reviewer.
To accept the invitation:
1) Click on the link to access an invitation-specific log-in page.
2) Log in using the email you want to be associated with that review.
This can be different from the email the invitation was sent to, but remember the invitation link can only be used once!
