Stickums is a shareware program that allows you to place stickums (like sticky notes) on your computer desktop or on a stack of stickums (referred to as the NoteStack). The NoteStack may be hidden from view. Stickums are equipped with password protection and alarms and may be transferred across a network or e-mailed. Each stickum is customizable in background color, background image, text color, font and general appearance.
