Suggestion re previewing messages

[bob_32_116]

If there were one improvement I would make to the board, it would be that when previewing a message I get some sort of visual cue that what I am looking at is only a preview, it has not yet been submitted.
I cannot count the number of times (on this board and others) that I have composed a lengthy posting, previewed it to check for errors, perhaps edited it a couple of times, then thought "OK that's fine" and left without submitting the thing! Most of the time I feel like a stupid dickhead (perhaps I am), but cannot be bothered composing the thing all over again.
Perhaps a flashing border - or a pink background to distinguish it from the white background of messages that have been posted.
