Domain problem

[terro]

hey guys, I only need to provide subdomains to my customers, which means that they should use my own main domain. How to configure this? Please help me.

create a reseller account for yourself. click the "switch" hyperlink on that user line to switch to that reseller account.
with that reseller account create a user account for yourself and switch to that user account.
with that user account "manage domains" and create you subdomains.
