Hi Charlotte, I'm really sorry about what you all are going through. He's such a superb guy and it's people like him that make this forum such a wonderful place to visit. As far as private messages, up a little closer to the top of the page on the right, you should see "Welcome, Tweety... and under that is a link the Private Messages". Hope that helps.
We will miss him while he's recovering but we are all glad that it turned out to be panic attacks and not anything more serious.
Don't be satisfied with what you can do but rather strive to do the things you can't do!
