A method of running an interactive multi-user application at a terminal of a communication system, according to which the terminal accesses a server of the communication system to create or update thereat, using a set of application-agnostic tools implemented at the server, a slave process corresponding to the interactive multi-user application. The device comprises a fluid reservoir, a length of hollow tubing that will be attached externally to the handpiece, and a nosepiece connected to the tubing. The fertilizer spike is also provided with a soil abutment surface that is adapted to hold the fertilizer spike in the soil when the tool is pulled away from the fertilizer spike. Related methodology is disclosed. Furthermore, there are provided vias of either through-holes, blind holes and buried holes filled with a conductive paste material to form electrical interconnections with conductive layers of the printed wiring board.
