• further receiving from the one of the banks via the computer network signals to create one or more named groups of prospective participant banks from enrolled SMBs and to authorize transmission the participation opportunity to at least one named group,
• automatically authorizing immediate access to the participation opportunity, by the prospective participant banks belonging to the at least one named group and accepting requests additional information, when supported by a mutually acceptable confidentiality agreement;
