Aggregation apparatus that comprises a computer, a display controlled by the computer, and networking hardware connecting the computer to a network. The computer is programmed so that the aggregation apparatus connects to a plurality of sites on the Internet, authenticates itself with each of the sites, and attempts to retrieve information from said sites. The information comprises different data types. If no error is detected or trapped, an aggregation of information is produced and rendered as output. If an error is detected or trapped, an attempt is made to associate the error with an error code. If the error code is associated with the error, then the aggregation apparatus communicates an instruction to a user interface to trigger presentation of a message to take an action. If the error does not match an error code, an instruction is communicated to the user interface that a particular action has occurred.
