The PM (Private Message) system just got a new feature. It's called "Labels", which is similar to "Folders"...
Similar to folders. You get the benefits of folders, but with one added bonus -- you can apply more than one label to a conversation. Instead of having to pick one folder to hold a message, you can access labeled messages from your inbox, 'All Mail,' and from all the labels that you assign to the message.
I created a new "Label" named "Saved", then labeled any important messages that I wanted to save with that "label".
A message can have several labels. You could then Make a Lable called 'Friends' and one Called 'strangers'. And add a "friends' and 'saved' label to a message.
All messages start with the "Inbox" label, which you can remove, after you have added another label (like saved), then the message will no longer show up in your inbox, just in the "saved" area.
Remember ALL messages, Inbox, Outbox, and in your labled areas ALL count toward your limit.
