These functions, under Maintenance / Online Reservations / Reservation Friend, will send full availability information to Friend, or request a full download of reservations and availability from Friend. These can be used any time (form the Friend Master only), but should only be used for initial synchronization or when a problem is suspected.
When invoking one of these two functions, a results window will be show if you wait for the response (e.g. don't open any other dialogs before the reply is received). Depending on the size of your park and number of reservations, it may take a few seconds to several minutes.
