• Ever wonder what that warning symbol you see after some links on Mahalo is? It's our warning symbol. This list of Mahalo Warnings should give you a basic idea of what we're trying to warn you about. Sometimes we'll warn of aggravating things like pop-ups, while at other times our warnings will be more informational. Each Warning example below appears as it would on a normal Mahalo page, followed by the text that it includes, followed again by the actual code we use to put the warning after a link.
