 Primaries:
 * As soon as possible, initiate discussion with the other reviewers in order to reach a consensus about whether the paper should be conditionally accepted or rejected for publication.
 * Ensure that all reviewers contribute to the discussion about the paper. Consider emailing external reviewers directly if they are not responsive.
-* By the end of the discussion period, write a summary review with a recommendation of conditional acceptance or rejection based on the reviews and the discussion. *This summary review MUST explicitly spell out what the conditions are for turning a conditionally accepted paper into an accepted one.* The authors need to know what is required of them as well as what comments they should consider but that aren’t required to address. If you and the secondary reviewer cannot agree on a recommendation for a submission, please document the discussion in the confidential portion of the summary review. If views have changed or consensus cannot be achieved, please let us know why in the confidential comments. **Summary reviews are due on May 15.**
