Abstract: Method for enriching content of a web page (2) displayed for a user on a computer (3) connected to a computerized network (5) and provided with a web browser (4), said method comprising the steps of: the web browser (4) sending a request for a web page (2) to a distant web server (6), upon receipt of the web page (2) from the web server (6), the web browser (4) parsing the web page (2) for contact information, upon detection of contact information within the web page (2), the web browser (4) sending a request for presence information (8) associated with said contact information to at least one presence server (7), upon receipt of the presence information (8) from the presence server(s) (7), the web browser (4) displaying the web page (2) on the computer (3) together with the presence information (8).

Abstract: A computer implemented method for user-enhanced ranking of messages, the method comprising: receiving a datastream, the datastream comprising a message generated by an end-user, an identifier of an earlier message and an attribute defined by the end-user, the earlier message being stored in a computer-based database (4) comprising a collection of messages interrelated by a collection of directional links, storing the message in the computer based database (4) as an additional message of the collection of messages, generating a link in the computer-based database as an additional link of the collection of links, the additional link pointing from the additional message to the earlier message, storing the attribute in the computer-based database (4) in association to the additional message, and computing a link-based rank for the earlier message as a function of the collection of links and the attribute associated to the additional message.
