This article will explain the difference between these roles and what each one means in terms of access and powers within the system.   ### Chairs and Assistants   Chairs and assistants both have complete control over the dates and settings of the system and can also edit submissions (or add/submit them to the system at any point). They can add and invite reviewers, allocate and edit reviews, and send messages from the communication system.    The only difference between the two is that if you use the '\[\[ChairNames\]\]' macro in an email it would list the chairs, but not the assistants. You can learn more about using macros in the Communication Centre [here](https://help.exordo.com/using-macros-to-enter-information-in-emails?hsLang=en).   ### Track Chairs   Track chairs are limited to just the [track(s)](https://help.exordo.com/explaining-tracks?hsLang=en) they are added to. They can see and edit submissions on their track and also email authors. They have full visibility of all submissions in the Initial Submissions hub for their track only. In the Review hub Track chairs can add and invite reviewers, allocate submissions, start the review process, edit allocation, assign and unassign reviewers and also email reviewers. They can disable the review completely or close the review if needed.  Their role also allows them to save final decisions on the Reviewed submission and notify authors about the Acceptance. Track chairs can also generate all the reports for their track.   They cannot view or affect anything outside of their own track. They don't have access to the conference's overall settings.   Only conferences which are running tracks (mini-conferences within the overall conference, not topics or themes) can add track chairs. You can find out more about [tracks and the power that track chairs have in this article](https://help.exordo.com/explaining-tracks?hsLang=en).    ### Data Viewers   Data viewers can see all submissions in the system in all the conference stages (Initial, submissions, Review, Final submissions, Presentations and Schedule) but they cannot make any changes to the system settings or submissions.  They have access to all the conference exports.  ### **Review Group Chairs**   Using [review groups](https://help.exordo.com/explaining-review-groups?hsLang=en), a conference chair can delegate the responsibility of managing the peer review process to individual review group chairs. Review groups don't see the Initial submissions hub and are limited to the Reviews and Final submissions hub only.    A review group chair can be responsible for: 1. Adding and Inviting reviewers. 2. Allocating reviewers to submissions. 3. Re-assigning declined reviews to other reviewers. 4. Reminding reviewers to complete their reviews. 5. Submitting a final recommendation/report for each submission. Essentially, the review group chair manages the peer review process for a given set of submissions and may be asked to submit a final report to the general chair or track chair. They cannot affect anything outside their assigned set of submissions. Review group chairs can export Review and Reviewers data for the Review groups they are managing.   #### Session Creators   Session Creators is the role that can be assigned to track chairs. If used, the session creators can build sessions out of accepted submissions on their assigned track. Admins can then schedule the sessions.
