#_BOOKINGNAME Not available at guest registration

Dear all,

Great plugin!

Please help with the following issue:

In a guest registering scenario, when someone orders a ticket, two automatic emails are being generated to the Customer: one for the registration, the other to provide the booking details.

Unfortunately, the #_BOOKINGNAME placeholder works for the booking email, not for the registration email.
What placeholders besides %username% (which is the front part of the Customer‘s email address) can be used to welcome/name the new Customer in the registration email?

Thanks and best regards

Michael
