I sent a radio dj a mesage and when she replyed she put on the end her name and then x. Dose that meen any thing? And shuld I send one back with x on the end.
Putting a "kiss" at the end of a message is just something some people (especially girls) sometimes do - it doesn't really mean anything and doesn't mean you have to respond in kind. Just be grateful it wasn't Chris Moyles. :-)
Quite agree - some people just use this as an 'informal' signature.
I sign e-mails to my regular photographer with an 'x', as does she, but there is absiolutely nothing to be read into the action by either of us, it's just more friendly.
