Your rsvp option takes people to a Add to your Calendar option that is set on Eastern Time. This does not work for us being Mountain and it is confusing our participants. I have heard from others this has been an ongoing problem. If it is not resolve very soon we will have to discontinue our contract with you as it is causing us a lot of chaos with our invite list and time. Either the add to calendar must be disabled or you have to get your time zones right. I have been told by others this has been an unresolved problem for some time. We will wait until mid- November and then make a decision on our mail program.
