A question we get quite often is whether a parent can use a single email address to sign up and manage Agencyclick availability for several children.
Agencyclick requires a unique email address for each new performer listing - the following workaround for GMail makes use of a plus sign to extend the original address (eg. the parent's address) to satisfy this requirement.
Example:
joesmith5@gmail.com is the main (parent's) address
joesmith5+mary@gmail.com is the first child's sign-up address
joesmith5+harry@gmail.com is the second child's sign-up address
joesmith5+samantha@gmail.com is the third child's sign-up address
Email sent to each of these three addresses will arrive in Joe's Gmail inbox.
