When they log into the platform, all they will need to do is click on Manager.
There will be a section labelled Upcoming ILT Timeslots that shows ILTs coming up in the next two weeks that contain users they manage. Clicking on the envelope icon will let them send messages to the users.
They will see a list of users, together with their current status in the ILT time slot. They can then choose to either Message All Users, or select specific ones using the dropdown menu. After filling in the Subject and Message, clicking on Send will send the message to the selected users.
