I activated the reunion registration feature. I am using it as survey and not an official registration feature, that will be done by US mail.

However, when it is used and a person indicates "No" on the Planning to attend question, it records a "Yes" in the profile. Did I do something wrong in the setup? Shouldn't the No answer cancel the Number Attending?

Attached is how it appears on my iPhone and the Profile page. The Memory Book selection appears twice on the iPhone message, but only once on the report.

That is because when someone answers these questions in the Reunion Planner, they are technically (as far as the system understands), registering for the event. If you want to use the system as a survey, I suggest using the survey maker to do so and not the Reunion Planner.

If I create a survey, will it post the attending results in their profile, like the planner does?

If not, I noticed that I cannot change the information in their profile, can the classmate do it or undo the registration?

And, since the registration feature is now live, what other issues may I be looking at if I change it now?

The classmate will need to do that. I can't think of any "other issues" per say.
