With a Prism group subscription license, if someone else will be assisting you with managing and/or distributing your license, you can set that person up with admin access to your Prism account. Here's how:
You can set up an alternate administrator to your group license from directly within your Prism account. Just sign in at http://graphpad.com/myaccount/ and then click "Group Profile". Add in the email address of the alternate administrator(s) to whom you'd like to provide account access.
The new admin(s) then needs to go to http://graphpad.com/myaccount/ to register for a new account and set up their password (there isn't one set up yet, so this step is necessary to get a unique password set up for themselves). Once they've set up an account, they can sign in directly to the Prism account at the link above to access your group license.
