How do you add someone with a @mac.com or @me.com address in iChat?

 

Ralph Johns comes to the rescue.  It is surprising and confusing that they have chosen to implement it in this way. “What you have missed is the fact that iChat 5 does that one bit differently.

As Apple IDs and certain other ISP email “addys” are valid AIM Names, you just now type in the thing, not having a drop down for @Mac.com and MobileMe”
