\label{Slot_About} A course coordinator can add slots, by pressing \textbf{parm} (Managing Parameters) on the main menu and then clicking on the link Managing Slots. The link will guide you to a page showing all available slots. You can control which slots to show based on opening date, as well as what slot information to show. There are two ways of creating slot, using the web interface in LON CAPA (see Adding Slot Using the Interface \ref{Slot_AddInterface}) and uploading a comma delimited file. Uploading a file allows you to use other applications in creating a comma delimited file, and automate the entry of multiple slots (see Upload Slot File \ref{Slot_CommaDelimited}). Each slot can be edited or deleted according to your needs (see Editing and Deleting Slots \ref{Slot_EditDelete}). When a slot is deleted, students cannot use that slot anymore, even if they have been scheduled to take it before deletion.
