Thank you Wizard,
I`ll probably use this feature,
however - I meant in general - even if the hosting doesnt allow addon domains ... is there really a problem - I dont understand if a domain can be redirected to any URL why should the domain company care if the user`s hosting supports Addon domains or not.
In example if I have hosting from company "A" and have a subdomain "sub.domain.com" hosted there,
why would the domain seller (company "B") be interested if A supports Addons, after they can only redirect the domain to the given URL and nothing else.
