Please change the chat sound to something less intrusive and add a sound for player joining.
I think I can't be the only one to always mute the text/chat message when making a new install. It's like a combination of some really loud old fax machine/printer and an alarm.
A light beep , quite muted, would be best. I think. Or almost anything else. Like most of the other sounds though!
One I would like to see added is for a player joining a lobby. Sometimes you just want to alt tab and while slapping is there, it would be great to know immediately when someone has joined. One might even want to have slapping muted sometimes but joining on.
Sm0l suggestions, dunno if it needs its own thread, feel free to move it somewhere if it doesn't.
PS: A volume slider or slightly lowering the overall sound would be good too as its set quite high in relation to other applications.
