Can I give access to a single forms submissions to another person?

Yes, you can give access to the submissions of a single form.
One way to do this is to use the Sub-User Account method. You can give access to an existing user or to a new user. You have the options to select which form you want to give access to and what kind of access (view, edit, or both).

Another way to do this is to make the submissions page of that form public but you have to set a password.
