Well, PM (Private Message) system was causing me head aches all the time. Even "DELETE" action button was doing dancing and hide and seek. I got fed-up with it. So, finally I decided to follow two different paths depending on the situation:
1. In some cases, I opened a Word file with name "Ottawan-MemberX.trade2012". Every message to or from MemberX was copied from PM and pasted chronologically in the named file. Only the last message was left undeleted from the F4F PM location. This way I have all record chronologically available in one file. The last message from the PM location is deleted when used for reply. Personally I found this easier.
2. In other cases, I decide to give my email addess for direct communication bypassing the PM.
