I'm setting up our website for our 35th reunion
When I look at the classmates list, there is a link called "attending reunion" which is left over from our 30th.
How do I clear the list so I can start over again?

You don't want to use the same Reunion you used before because the ATTENDING information is still around.

On your Reunion Planner page, click the PLAN A NEW REUNION button. This will create a new reunion and clear all of the attendee information from the previous reunion. If you already changed the EDIT/details information for the new reunion in the old reunion, just copy/paste it to the new reunion.
