ArenaNet:Guild Wars 2 suggestions/Online/Offline system

Online/Offline system (Discussion)
All players have a friends list. In that list you can see who is online, and who is offline. Apparently, you can only notice that when you view your friends list. Many players don't even notice that there are friends online while they play, which is an annoying fact. Now, if players would get a message containing information about a friend turning online/offline, it would be handy for us to notice our friends. Also, inserting a sound for this message makes it more noticeable, however, it's not necessary.


 * Why this is a good idea
 * Players can notice who came online or went offline easily.


 * Why it may not work out
 * Might be annoying for some players that like a clear chat with a little amount of messages (avoided if the feature is optional).
 * Annoying for people who don't want their friends to be notified when they log on -- ie, people with a lot of friends, or people who are conducting a lot of auctions trades, who don't want to be PM-barraged as soon as they connect.
 * No stalking please.
