You asked for it, you got it. We now have online status indicator for instant messaging. You can now go to a users profile and see if they are online with most of the popular instant messaging clients.
All you have to do is go to your profile and fill in the information for any of the instant messaging clients you use (and want others to know about). When others view your profile page they will then be able to see whether you are online and accepting chats. You can use the privacy and blocking features of your chat client to minimize interruptions if necessary.
I hope you find this new feature useful. Let us know what you think!

If that's all it takes...
Just a nit-pick but MSN
Technically speaking...
