I need a program that syncs Facebook messages to my PC.
In Windows 8(.1) you have the Mail app with which you can easily read your emails. It also notifies you when new emails come in and it downloads your emails.
I need a program that does the same, but with Facebook messages (and Windows 7).
Very important to me is that the program makes an offline copy of my messages inbox, which I can read even when they are deleted on Facebook itself.
Is there a program that can do this? And if there isn't, could anyone suggest another way to get notified of new messages?
