I believe an excellent functionality for the updates field would be the ability to "tag" an email address in addition to the current functionality of tagging a Workfront user. There are multiple situations in which clients need to know the status of work being done against a task, but cannot be tagged in updates as we're not going to make 100s of client Workfront accounts. Allowing updates to be sent to an email address typed directly in the "tag" field would be a great tool to avoid extra leg work in advising clients of updated statuses.
