[darthclark]

I am trying to figure out how to change the domain registration that can be showed to customers who login to their plesk control panel, and click domain registration or one associated it will take them to another webstie of my choice.

also how do I change the webmail program that is used currently with plesk? i have modded squirrel mail program that I would like to use instead, so when they click the webmail link it will take them to my webmail program.
