In cases when you need to introduce certain similar changes to several client accounts, you can use the Group Operations function, made available to simplify administration of multiple accounts. Using this feature you can, for instance, select a number of clients, enable all of them to create domains and limit the maximum number of domains to a specific number - all that within a single operation, without having to select each client independently and edit his/her settings.
To perform group operations on client accounts, follow these steps:
Select the Clients shortcut in the navigation pane. The page will open displaying the list of registered client accounts:

Select the clients, whose accounts you wish to modify by checking the corresponding checkboxes.
Click the
Group Operations icon. The Group Operations page will appear, divided into three groups:
To set permissions, select the Do not change, Enable or Disable radio button for the corresponding type of operation.
To edit limit settings for a particular resource type:
First, select the desired action from the drop-down box:
Then, specify the value of the new resource limit in the corresponding input field.
If you chose to increase/decrease the presently set limit value, use the drop-down box to select units if you wish to modify the limit value by a quantity of commonly used units or % if you wish to modify the limit value by a particular percentage.
Click OK to apply the new settings to the selected client accounts.
