I did a lot of search and found that there were some PHP code hack in the year of 2012 discussion.
But later discussions are saying that Face-to-Face are meant to be for one session only registration. If someone wants to re-register for a future session, they would have to be marked as "No-show" for the session that they registered before.
However, we have very large population of participants and very few people to actually watch the attendance. It would be hard to compare each person and mark people who didn't show up as no-show. Is there a way to just open up the registration list to allow multiple signing up?
Thanks!!
