Since Mambo the infamous mambots did the hidden dirty work on the developers behalf. There are several flavours of Mambots (Plugins) : System, editor, content. Each must register one or more functions hooked on several system events. We tried to find a chart of these events and the availability in the several distributions out there, but we could not find any. We sistematizated the events for the three major releases (Mambo 4.6.2, Joomla 1.0.15, Joomla 1.5.2)
