I posted a WL book and the intended recipient wants to know if it's from a smoking home.  I'm not the first one to have the book, so I have no idea.  How can I PM the person to make sure they want it?  I don't see an option to do so.

TIA!

You can't PM them unless you accept the request first. If you do not know whether your book meets their conditions, you are supposed to just decline. Your book will go on to the next person on the wish list.

If yours is a nonsmoking home and you can't smell any smoke on the book, accept the request and then PM the member to see if it's OK with them.  Chances are, it is (said by someone with a nonsmoking condition on her account).

Does the request say something like "I prefer books that are not in a smoking home"?  If so, then you are most likely safe sending it if it doesn't smell like smoke to you.  Many of us use this type of phrase to mean, I would like books that do not smell of smoke, but understand you may not know if it has ever been in a smoking situation.  Some people are ultracautious (many times, needlessly) about sending to anyone with conditions, and will interpret any non-smoking request to mean "ever been in a smoking home," which is nearly impossible to verify for a used book.  There have been many discussions about this, and I do not think most who wish for books "not in a smoking home" mean "ever been in a smoking home" but rather "not in a smoking home at this time"  That said, it's fine advice to ask after you accept the request.

Thanks for your replies.  The requester actually asks the question....as if I can answer.  Frustrating.  I am going to go ahead and accept and PM the person.  I guess they can cancel if they want.  There are plenty of others who want the book.

If they cancel the request they lose their place in the WL line. So it's hard to say.  It's not fair to ask you to PM them first.  I hate to say it but if they asked me to PM them first and didn't include their name or PBS nickname-I would probably deny it and pass it on to the next person. But it's your call. I buy used books all the time and have a non-smoking house. I accept requests with a non-smoking requirement even if I got the book used.  I have yet to buy one that smells of smoke.   If you accept and then PM be prepared to wait for them to respond-not everyone checks their account everyday.  If  they don't want the book and you cancel to preserve their place in line, it will get offered to them again when you repost, then you'll have to decline based on conditions to get it to move to the next person. 

Edited to add: you are not required to provide the provenance of the books you post. 

This is why, in my RC, I include my name and my screen name, so if there's any questions, they have a way to find me.  Good reminder folks.  If you have RC, include your screen name so you can be contacted.

If you don't smoke and can't detect any smoke odor when you smell, it should be fine.  Go ahead and accept and PM them to let them know that even though the book wasn't "new" to you, you can't detect any smoke smell.  You can always cancel if requestor doesn't feel that assurance is good enough, but I bet it will be.
