When new users are added to products or invited to Aha! (specifically paid users) send an email to the account and/or billing administrators to let them know who was invited along with the user who invited them.
Thank you for the idea. Part of this idea has since been added. When a new user joins the account, an email will be sent to the user who invited them. Given the low volume of support for this idea, we do not have plans to make updates in this area at this time. We hope you can understand.
