Is it possible to share the submissions with anyone?

Also is it possible to share results with anyone or must they be users?

thanks

Yes, you can. Either by sharing the form submissions page:

Or, creating a report like HTML Table/Grid Listing and sharing the report link:

You can also share the submission to someone as your sub-account user. Here's how: http://www.jotform.com/help/232-How-to-Share-Forms-with-a-Sub-Account-User.
