Your resellers have different levels of technical expertise and,
therefore, may have problems with managing certain settings of their
subscriptions. You can log in to Plesk under a reseller’s account to
assist your resellers and change the settings of their service plans,
customers, and subscriptions. To start managing a reseller’s
subscription, find this subscription in the list on the
Resellers page and click Log In as Reseller. To switch back to
your account, click Back to Administrator at the top of the page.
To learn more about improved navigation among resellers and their
customers, domains and subscriptions, see Quick Navigation Among Plesk
Objects.
