The Export operation provides a rich set of data, in spreadsheet form, for a set of meetings or for a single meeting, including the list of those who have signed up.

The “.xls” file thereby created can be opened in Excel or some other spreadsheet application to show several sheets, as follows.

• Attendees’ Schedules [for meeting organizers]: a datasheet with columns that show the meeting’s details, with one row for each meeting attendee signed up.
• Events Overview: a chart of all meetings selected as they appear in the Meetings page.
• For each meeting, a named sheet
• Chart showing the meeting title and details, plus a list of attendees [for users with that privilege], the wait list, and comments.

Creation of the Sign-up tool was motivated by requests from faculty who wanted to replace the "sign up sheets on the door" with an online alternative. Faculty needed a system that would allow students to sign up for office hours, meetings, review sessions and other events in one convenient place. This tool can also be used in project sites to create meetings for the participants.

Various scheduling, participation, recurrence, and notification arrangements can be made.  An instructor can assign participants to timeslots or allow them to select their own choices.  If a timeslot is full, the instructor can allow participants to add themselves to a wait list, which automatically "promotes" a participant when a slot becomes available and sends an email notification.  The Sign-up tool is group- and section-aware which gives instructors the ability to set up office hours or meetings which are visible only to their sections or to a group.
