How to add more domains and host more than
one website on myIOP webmaster hosting account?

You can add up to 10 domains. incl. your primary domain within your myIOP panel.
This means you will be able to host up to 10 seperate websites on your one myIOP account,
however this does not increase your account's bandwidth, disc space, network traffic, door pages
or search engine submissions. If your additional sites get busy you may need to switch to a seperate
myIOP account to accomodate your site visitors.

Fees per month:

US$ 1.95 per month | per 1 domain

Set Up Fee one time:

US$ 19.95 per domain

log in your myIOP webmaster panel, click in "Add Services" and choose "Add domains".

Your domain allowence will be updated in your Plesk server panel within 24 hours.
Then you can set up your additional domain names.

Don't forget to adjust the nameserver settings for your domains you added:
