For participants
Reviewing papers (reviewers)
Accept an invitation, work your queue, and submit reviews.
This guide is for reviewers on a conference program committee.
Accepting your invitation
You'll get an email invitation with a link. Opening it shows the event and your role; sign in (or create an account) and click Accept. You then land in the event's dashboard. You don't need to be part of the organizer's company — the invite is enough.
Your review queue
Open Reviews → My reviews. It lists only the papers assigned to you, each with a status (pending, in progress, completed) and its deadline/countdown. You can opt out of reminder emails per assignment.

Writing a review
Open an assignment to get a side-by-side view: the paper on one side, the review form on the other. The form is what the organizers designed — typically an overall score, comments to the authors, a recommendation, and confidential comments for the committee. Your progress autosaves; click Submit to finalize. Once submitted, the review locks.
Comments to the author are shared (anonymously) with the author; confidential comments stay with the committee.
Conflicts of interest
If you have a conflict on a paper, use Declare COI and give a reason. That removes the assignment and prevents you from being re-assigned to it.
Your areas of expertise (used to match you to papers) are set by the organizers on your reviewer profile — mention them to the chairs if they need updating.
