Editing a plan
You can modify an existing plan at any time. Changes to an existing plan do not effect accounts that have already been created by that plan - the changes only apply to new accounts created using this plan.
To edit a plan:
Click on the Plans link in the navigation area.
Click on the [Modify] link next to the required plan.
Edit the details of the plan as required. Refer to Plans for more information about specific fields.
Click on the Update Plan button.
