Keep track of organizations and other institutions using tags. You can enter the organization into you database as a new person, and then use a tag to designate that it's something else. The tag could read "org", "organization", "church", "non-profit", etc. You can also create a specific tag for that organization, say "Peoples_United" or "PU", and then not only tag the organization but also tag everyone member, staffer, or other close affiliate with that same tag.
