If you don't lose your post/PM/e-mail when you hit back on your browser, chances are your computer isn't as secure as you might like.

But don't we have a setting somewhere in our "preferences" that can, uh sort of force you to preview your posts and such?

Maybe just theinstinctual hitting of the button will cause you to go "oh smack, I forgot my subject", and then, lo and behold. . .your PM's still there?

I don't know. It might eat your PM anyway. I don't know whether the "preview" can actually overpower the awesome force of the Ire of the Untitled PM.
