Hello,
Ideally, you would like the new user to be able to access your Splunk instance and, they would be able to view the dashboard you have created and the content from your instance. You would be able to control the data they have access to by updating their role/profile.
If your users need only to review the results of the dashboard; the best way would be to send the dashboard by email to them. They would use their Splunk instance for other work and review your Dashboard results, on the schedule you decide.
You can find the details here:
http://docs.splunk.com/Documentation/Splunk/4.3.2/User/ScheduleDeliveryofDashboardPrintoutsviaEmail
Another option, if you would like to share the format of you dashboard (without the data), one of the possibility would be to copy the XML of your dashboard. Once the new instance is deployed, you will paste the XML in the Dashboard editor.
There are some reference to in our Docs about using XML to created simple and advanced dashboards
http://docs.splunk.com/Documentation/Splunk/4.3.2/Developer/AdvancedIntro#Simplified_XML_and_Splunk....
Finally, you can integrated your dashboard into a Splunk App.
It might be too much effort for sharing a simple dashboard but depending on how many users you are planning to deploy, you might reconsider that.
I am sharing the link to our Documentation, in case you would need some reference about it:

Thank you,
Lionel
