From a NY Times piece that claims a shared workspace will keep family members on the same page:
Take a large, old frame from a flea market or your attic, cut a corkboard to size, cover it with fabric and place it in the frame. Tack pieces of ribbon on the corkboard to create separate areas for each family member, or do individual frames for each person.
Personalize a dry-erase board the same way — put it in an old frame or place pieces of wood molding around it. Carendi also recommends painting a section of wall, or even an entire wall, with chalkboard paint to create a huge space for messages and schedules.
