Sharepoint - Add users (superusers) to Distributed Service account

Hi There

I was reading this MS Sharepoint article (http://technet.microsoft.com/en-us/library/ff758656.aspx)  

on "superuser" accounts for Sharepoint. These two accounts are setup for the Distributed Cache Service.

What I want to do is remove the current farm account on the Distributed Cache Service. And add the two superuser accounts instead.

More info: http://www.gsoft.com/en/blog/configuring-administrative-service-accounts



In summary what I would like to know:

1. How to view service accounts for services such as Distributed Cache Service and App Fabric Cache service.

2. Change the accounts for these services and the super user accounts.

**If you read the above link you can see that there are two superuser accounts associated to the Distributed Cache Service.

**With relation to the first Microsoft article I have already created the super user account just need to add them to the distributed Cacher service.

If you require additional info please let me know.

Best,
J3di
