More than once have I tried to get some of my online friends to see if they were available. Sometimes, when they come online, the meeting scrimmage I had tried to get out, had already ended b/c I was not able to contact them. I was thinking If we could have a message portion where we could use our emails and write a message to a friend without knowing their emails for privacy. It's like the same on social networks, where if you know someone on FB, but they do not know your name, you can always send a message to them for them to remember who you are. I hope a messaging system will come soon, so that I can contact some of my friends when they are off line and will be able to see that message.
