As you can see in my signature line, I have a message regarding a free book I am offering.  If I want to advertise this offer in the book bazaar by putting this information in the body of my message but not the signature line, how do I do so?  I tried taking the signature line away, posting the message in the book bazaar, and then adding the signature line again later (after the message had been posted), but I have found that when you add a signature, it adds it to all your posts, even earlier ones.

Hope what I am asking makes sense.  It's just annoying me to advertise a book in the body of my message and then have a repetition of that information in my signature line.

Thanks.

Edit your message to say see signature. You cant make the signature leave just one message its static it follows all of them no matter what.
