Thank you for doing this!
I had the following conversations going that know have missing PMs, or in the last case that possibly does:
To/from Dogman, subject "Contact Info" (IIRC; none of the messages are visible to check, but at least one of the messages contained the word "phone" or "number", another should contain the word "address" or "phoenix")
To/from Cvin, subject "Prodeco battery"
To/from Thoroughbred, subject "Alltrax contoller and other zero x stuff, too"
To/from Incememed, subject " Hall Sensors'b'Gone"
I don't know what all of them are for certain, because there should be some unread ones in there. However, it is likely they are all in the same conversations, so probably contain the same subjects.
If anyone else sent me PMs outisde of that that I hadn't read yet, I dont' have any data to look them up with.
