In a preferred embodiment of the present invention, although not necessarily limited thereto, the system of the present invention may function in the context of an internet based commercial real estate brokering system. In such a system, potential buyers, sellers, lessors and lessees list and respond to offerings having characteristics as described in connection with the listings. For example, a potential landlord may, through interaction with the system of the present invention, list one or more buildings for lease. Communication and interaction may occur on an anonymous basis such that the potential landlord is unaware of the actual identity of the prospective tenant and vice versa until such time as one or the other or both decide to reveal their identity.
