I apologize that you received a multiple response from me to your single question. Ever since they revamped this website, about 50% of the time I get a failure of post delivery message. That sometimes is true..sometimes not. I have a supreme computer system and have no other issues with any other websites. The RC Universe response to this issue is related to AOL problems and popup blocker controls. I don't buy that. Again .....sorry ....happy flying.
