StickIt! is the world's first desktop to desktop sticky note. You build a group of co-workers, friends, family, etc. and then StickIt! to them until your heart is content. When you send a StickIt! note to a member of your group, the note will immediately appear on their desktop. The member receiving the note can leave the note up for as long as they wish or reply with a message of some sort. You can create as many groups as you like and invite friends to join your group.

Important Note: You will need to create an account with a valid email address in order to log in to StickIt! after downloading the program. Then, in order to actually use the StickIt!, you will need to invite friends to join your group. Until then it's just a pretty face.
