Return of Reckoning

In LoL I can queue and than alt-tab to a different window while waiting for game pop, and game windows comes to front with a big audio notification; so I never miss the pop.
In RoR if I dont keep the window up, I dont see whether I get a SC pop or not.

Is there anything that notifies with audio when you get a SC pop??

You can add Sirena (the file running) to your program startup list.

on Windows you do it by opening a Windows Explorer and typing shell:startup, then copy/paste a shortcut into it.
