Hi Tuan,
first of all thanks for the excellent component you made available and for the continuous development!
It would be extremely useful to add the possibility to send automatically an email when a registrant is checked-in.
Just think about sending thanks, the certificate, any other information based on custom fields or promotion to other events.
If you could just implement something like an email that can be customized like the other Registration Email Messages and can be enabled to be sent as soon as a registrant is checked-in, to the same registrant email address, this could be very useful in a lot of practical cases.
Looking forward to know if this is possible
Many thanks!
SR
