Phillip,

>I was thinking along the lines of "email shorthand" ie: rofl or eom or dno. Someone emails me with nbsp in the subject line quiet a bit and I don't know what she is refering to.

Oh. Well, it's hard to guess, without seeing the entire subject lines that she has sent you. How about:

Nice Big Smile, Please
Nothing But Sly People
Never Bring Stale Pizza
Note Below: Semi-Private
Need Boyfriend; Send Proposal

or maybe just a misplaced non-breaking space pasted from an HTML-based email reader?
