Failure to receive anything - has anyone had any luck?

[QPdoll]

I started sending out autograph requests last year using the suggested method and addresses from this site. I had mixed success, so I am wondering if anyone has had similar experience with those celebrities I didn't receive anything from. I wanted to wait to see if something eventually would come before I posted my "no responses". All of these had SASE or IRC's included with them. Would have been nice even to get a RTS or a refusal letter back so I could get my photographs that I purchased returned.

Joan Collins
Maureen O'Hara (I hear now she is no longer signing due to her advanced age)
Gina Lollobrigida
Deanna Durbin
Anne Rutherford
Connie Stevens was RTS on her fanmail address; I have resent to her other address
Ann Margaret
Dorothy Malone
Rita Moreno
Olivia De Havilland (again I believe advanced age)

Has anyone had recent success with these stars and if so where did you send to? Thanks
