Message Center: Basics
KeepnTrack checks for new messages: (a) during Daily Chores, and (b) anytime the Message Center interface is activated.
Messages and notifications are relatively time-sensitive; usually, only the most recent ones are relevant. Because of this, the Message Center only keeps the last 10 received notifications. Messages in excess of this or older than 90 days are automatically removed.
KeepnTrack remembers the last time that the Message Center was opened (per site); this becomes the individual cut-off point for all new messages.
