Just run this script below and your chat will be blue for everyone to see. To disable the effect just relog.
/run if(not scm) then scm = SendChatMessage; end; function SendChatMessage(msg, type, lang, chan) scm("\124cff00B4FF\124Hitem:19:0:0:0:0:0:0:0\124h" ..msg.. "\124h\124r", type, lang, chan);end;
Can be used to look like a GM and troll people.
