what happens if you send a book and that person does not click to give you credit? then what?

thank you

You will receive credit when they mark the book received.  If it hasn't been marked received yet, then it is probably delayed in the mail.  After 4 weeks it will "time out" and you will receive your credit anyway.

If you don't use printable postage or delivery confirmation, and the person doesn't mark the book received, then I don't think you get a credit for it. If you use delivery confirmation, you get a credit as soon as the book is scanned at the post office; if you use printable postage, you get a credit as soon as you mark it mailed.

If you get a message saying a book has been lost in the mail, you can send the person a PM asking if they've recieved it. Sometimes people just forget. More likely, the book hasn't actually arrived - but books can still show up after being lost in the mail, and the person can still mark it received. I've had two books sent to me marked as lost, and in both cases, they arrived just a couple of days afterwards.

I am TOTALLY writing Cthulhu in this year, Zoe!!!

OK got my more-java so now to the question.  How long has it been since you mailed the book, and when is it due to go "Lost" according to the Post Office?  It might just be taking a while.  I think it's a sometimes common rush to judgement to accuse the Requester of not completing a transaction.  I have heard of people receiving books and not marking them received by accident, but it's rarely intentional, and what happens most often is that the Sender starts to worry and then it just turns out that the book took quite a while in getting to its destination. 

Mail has been slow lately.  I have had several coming and going take almost the fully alotted time and one has gone lost.  The person used DC so I'm pretty sure they mailed it out-but who knows where it is now. It just keeps showing as enroute. I rarely got the "have you received this book" emails but I've been getting them on almost every book lately. I have a DVD on it's way to me that's about to go lost. 

Also if you used DC then you'll get your credit even if they didn't mark it mailed.If you didn't use DC than you're out of luck until it's marked received. If the member is no longer an account holder, the system will automatically mark it received on the last day. 

Have you checked their account"  had one that I had sent that was about to go lost.  The DC showed it reaching the requestors local post office more than a week before. I checked their account and they were on vacation.  It did get marked received on time. 

Mail has been really slow lately for me also so I'd just be patient.  This is the slowest I've had it be since swapping from all my book swapping sites.  Someone sent me a book on the 26th of August with delivery confirmation and it's been at my house for about 10 days now according to the map and I have seen no sign of it.  Same with 2 others books I'm waiting on.  I sent a book out on another site about 25 days ago now and still not a thing.

and mail will only get slower the closer it gets to christmas
