Faction member logging info

I've played other games that display a message either when a fellow faction member logs in or out and I particularly like this feature. It's helpful to be aware when people log in or out instead of having to scroll through the faction member list, shout in faction channel, or add them to your friends list (which, does the friends list even let you know when a friend logs?). This is particularly helpful when your trying to form parties for various things particularly bossing (I'm guessing maybe for TW as well although the faction I am a member of is still new and TW really isn't an issue at this point).

Anyway, just a thought as it came to mind the other night when I was playing and a faction member logged off and myself and others weren't aware.
