I think it would be neat if there was a way to indicate if someone was "Accepting" or "Declining" Valentines on the Valentine Exchange page.
The little "on/off" lantern would have 3 options: Off, Accepting, and Declining. Example: Selecting "Accepting" would give your avvie on the page a green border, or a tiny green icon next to your name, or...something small. (I don't know what would be easiest, sorry.)
Maybe something for next year?
