Site details: rename your site, review the time zone (this can only be set once, when your site is set up) and determine if your users need to use multi-factor authentication, like an SMS code or other one-time password to log in.
Site holidays: add and remove holidays applicable to your site.
Contact settings: define additional contact types, such as pager or home phone number, that users can enter into their profile.
Dashboard settings: define what to show on every user's home page regarding today's rosters — which ones to show, their order, and what details to include.
Communication history logs: see the system messages sent to each user over any time frame. Useful for auditing whether a user saw a reminder, and for counting SMS messages sent.
