I *heart* gmail

I've talked before about my love for Google, and they introduced another awesome reason why today. I composed an email to some fellow TAs explaining an attached powerpoint file for class tomorrow. I hit send, and gmail popped up a window:

You wrote "I've attached" in your message, but there are no files attached. Send anyway?

Forgetting to attach files is one of the major annoyances in my life. I am so glad gmail is looking out for me.
