Topic: What does "bidding" mean?

When talking about reviews, what exactly does "bidding" stand for?

Bidding is a phase during which reviewers can indicate their preferred papers ("wanted", "would like", "uncertain", "would dislike") and also conflicts of interest (see image below).

Use the bidding phase to allow reviewers to choose their preferred papers before you assign submissions to them for reviewing.
When you use the automatic assignment process, biddings take precedence over matching topics between reviewers and submissions.

This feature is optional in ConfTool Pro and often used for bigger conferences.
However, we recommend including a bidding phase for smaller events, too, because it can increase the quality and return rate of reviews.
