I'd like to post a list of the reunion attendees on our home page to encourage others. I'd either like to show the list of those who have registered. I would like to do it automatically so it will update, instead of having to manually keep the list updated. I see that this was done on the Broken Arrow High School example on your home page, but I can't figure out how to do it.

There is no feature to pull reunion attendee names onto your home page. The only place the list exists is on your Classmate Profiles page. Soon in the key you'll also be able to click the "Attending Reunion" link to see ONLY those Classmates who are attending your reunion. If you want them on the home page though you'll have to copy and paste them there yourself like Broken Arrow Highschool is doing.
