I just wanted to confirm with all of you experts whether a paperback front cover that has been folded back three times is not "excessively worn" under the posting guidelines.  Other than the cover, the book is in perfectly good used condition (i.e., no one would be fooled into thinking it is a new book, but it's in very good condition).  The cover is not torn, but where it has been bent there are white crease marks so it just looks a little beat up.  I'm pretty sure I can post it, and also pretty sure that the recipient should have no problem posting it, but wanted to get thoughts in case I'm off base.  Thanks in advance!

Crease marks on the cover are postable.  Not it isn't beautiful, but as long as they are not tears, you are OK.

Not excessively worn can be subjective. Although it's technically postable, I'd PM the requestor before sending and let them know and let them decide so no one has any surprises.

Thanks so much!

I would say it's not excessively worn.  What I do with books that I realize might be questionable depending how strict someone wants to interpret the rules, is that post the book, then when it gets requested, I send the requester a PM describing the book and giving them the option to decline it.   So far everyone (all two of them LOL) has said yes and when they got the book did not mark it RWAP, so I figure that is a good thing.
