something that annoys the shiat out of me when using either hotmail or gmail, is that if you try to attatch a .rtf, the damn thing pastes it into the email. Of course it wont actually do it in a way that might be remotely useful, it just paste's in all the formatting tags so it is unreadable, and it doesnt let you know what it's doing until you happen to mail yourself a .rtf.
If it sounds a bit petty to be annoyed about it, ask yourself what happens when some of your job applications are by email, and your CV is in .rtf for compatibility :disgust:
