I sent a member a pm thru the pm link on the Books I've Mailed page, to ask that they please marked the book received  (it was delivered 5/14).  However, that pm doesn't show up on my personal message page.  I mailed with pbs printable postage so received my instant credit for it.  If they don't mark it received and it is deemed lost by the post office, will I lose that credit??

No you keep the credit

That's weird, Adrienne.  I regularly message people by clicking the PM tab from the 'books I've mailed" tab and they always show up in my "PMs sent" list.

PM's have been problematic for me this entire pandemic! Last year especially, I was told by several friends that PM's that on my end that appeared "Read" were in reality never received! :P I still am never certain until someone replies that the PM actually got to them or was truly read. 

I rarely get Yahoo email notifications of new PM's. For some reason I seem to get them more overnight than during the day. I did just get get emails about 2 PM's. 

I hope everything works out with your credit, it should, Adrienne! :)

Not PM completed related but I have also wondered sometimes about the green or red light besides someone name. This is for those who choose to indicate whether they are logged onto PBS. Lol, I have no clue what I may have chosen for this! I have noticed that sometimes when someone has replied to a PM, at whatever time, the indicator light by their name still might not reflect that. So it has me wondering whether that is working properly either. 

As it happens, it was marked received shortly after my post.  They were out of the country til now .   All is good!!

I have oftened wondered about the green or red light besides someone name too.   I sometimes choose someone to reveal in a game based on who shows up as green/ online instead of someone who is red/ not online.

So glad all worked out, Adrienne! 

Good to also know it's not just me who wodners about the red/green light!
