Their inclusion there seems a bit counter-intuitive. At least to me. Maybe my brain is backwards. Maybe I should get some sleep, heh.
Seriously though, if that page is describing the features Helio has, I don't understand why someone who isn't even a customer yet, would need to know the nameservers. I would think the nameservers would be listed somewhere in cPanel. Then again, it's been a couple years since I last used a host running cPanel, and I don't know either way if its possible to edit the static cPanel content.
