just, to inform you, Ptrinchi is writing a plugin "Xevent" to launch an event with a specific date and time, you can also specify a variable everyday or everymonth...
there is also a command for this plugin, to create a trigger via xlobby with a specify date and time and an other command to launch the event in xxx min.
the plugin gives the possibility to receive imformation via a script or something else to launch an event: example if your hard disk is full, your script or codes should send information to the plugin to launch an overlay alert... but for the moment there is a bug that it prevent to use it correctly : look at this theard :
