A system includes at least one processor configured to provide a plurality of closed-access network micro-communities associated with a corresponding plurality of institutions. Each micro-community and corresponding institution may have an associated access list. The processor may display on user devices a user interface portal which is confined to the selected micro-community. The processor may receive via the user interface portal user data from the member users, which is instantly visible in the user interface portal to all member users. The processor may also receive via the user interface portal institution data from one or more administrators of the institution associated with the selected micro-community, which is also instantly visible in the user interface portal to all member users. The processor thus provides a secured-access open exchange between the member users and a secured-access feed from the institution to the member users.
