Been running 10.8 DP3 for a few days. Got my mail account all set up, iCloud, calender, stuff like that. I've yet to get any notifications to work on incoming e-mails or anything. Just upgraded to 10.8 DP4 a few minutes ago. Got Facebook and Twitter set up. Along with mail and calender etc etc. Still no notifications at all. Am I missing something? EDIT: No one?
