Instant Messenging Hyperlinks

[Wizkid]

Is there any way to create hyperlinks for yahoo messenger and msn messenger just like AIM works?

E.g., with AIM you can do something like: aim:GoIM?ScreenName=justincowling&Message=What's+up?

and I want to know if you can do that with yahoo and msn... does anyone know?

TIA


Edit: aim links don't work properly since fusetalk adds http:// to the front
