i can see i can email the requester when a new ticket is created/closed etc.

my query is:

not all our requester s want an email each time a ticket is created, only some do want the email

can i have it so SD will only email the requester s i choose without having to remove the email address's from the requester s who do not want an email?? or is it all or nothing?

suggestion: have a check box for email notification in the requester details????
