Currently users in YAWL do not have a field for their email addresses. Therefore it is not possible to write a codelet that could send emails to users for work item notifications.

The sendmail service could be used for this task, but an additional database containing the email addresses of user would be required to send mails to the user.

Ideally such a feature would be implemented in the resource service and configurable to send emails to users on offer, allocate or start events for new work items.
