It's funny, though, and I'm not directing this towards you or mean it any kind of mean-spirited way, but you can always tell Windows users from Mac users when it comes to sound on their computer. Mac users normally have their speakers on at some level, but if you ever send a PC user a link or whatever that might require audio to appreciate, 9 times out of 10 you have to also give them advanced warning about it, otherwise they just don't seem to get it.
Anyhow, welcome to the world of Mac, lugesm. Enjoy! 🙂
