So far, if you invite a new guest to a task, they receive the invitation, but until they join the workspace by registering, they will not receive any notifications for changes to the task. We would like this feature, because we do not expect all of our guest users to immediately register when they receive the invitation, but we would still like to keep them up to date on the tasks.

Also, guests should receive E-mails when a new task is shared with them.
