How do I force some of my domains to go to a specific parking service?
From within the Portfolio Manager, click on the Folders link. Add a new Folder and provide it a name that means something to you. Then click the Edit link for the folder and choose Custom Settings. Set 100% to the Parking Service you want to use or choose multiple services totaling 100%.
Note: You will have to move the domains into the folder for the Custom Setting to take effect.
