The mailbox appears on the very far right of the screen, running off the screen (Firefox). It seems very hard to notice. The text was the same way. I actually liked the popups - partly because I never leave unread messages. It also has the annoying habit of "sliding" down the screen if I scroll so it is always visible (or at least 1/2 of it is).

The box (or some indicator) would be better if it was more in the middle of the top of the screen. My guess is that I'll "miss" new PMs about 50-60% of the time.

"The heart is the main thing in true religion...It is the hinge and turning-point in the condition of man's soul. If the heart is alive to God and quickened by the Spirit, the man is a living Christian. If the heart is dead and has not the Spirit, the man is dead before God." (J.C. Ryle)
