We really need the Email batch MOD/ADMIN functions for events like member finishes batch, member submits batch quiz, etc, just like regular instructor emails in WPLMS.
Well im sorry batch specific emails to moderator/admin of batch is not available right now.
But remember it would be very heavy processing :
we need to fetch all batches of the course and then fetch emails of all admins/moderator of batch for this .
w e would try to add it in future updates of batches plugin .
PS : nice suggestion :)
