You can install digistore on as many sub domains and sub directories you want, but of course you will have to install joomla on each of these sub domains/sub directories.

I can't give you more advice without knowing the nature of your business. If you give more details, that would help.

Hi Lemonbar

You can use one Authorize.net account for any number of shopping carts or installations of Gigistore with one checking account.  That is what we do.

I am not sure your idea is structured the best way in order to maintain your site.  We are setting up Digistore to offer access to some products while normal store users will never be able to see those.  But our sites look the same too.

I would have Digistore on only one Joomla installation.  if you have more than one Joomla site just make each site match up to a category in Digistore.  This way you will only have one SSL, Auth.net, and Digistore to manage.

No, these are not sub domains, these are top level domain, because they end with ".com". Sub domain is what comes before the top level domain.

For example:

demo.ijoomla.com is a sub domain of ijoomla.com, but ijoomlar.com is a totally different domain, even if it sounds similar.

If you told me producta.mycompany.com, then yes, that's a sub domain.

How many CPanels are you using?

Hi,
   how are you accessing this domain organicbabysocksonline.com ?
Open this URL in your browser and you'll only get nothing or redirected to a google search listing this forum thread.
An ad-on domain is a free domain registration that is provided with some hosting packages.
you can only access a domain like organicbabysocksonline.com if it has been registered. Otherwise, you would not be able to access it at all.
So, lets try to clear this up, the licnesed componetns must be installed on the final resting place of the users browser.
For example, if you have demo.mysite.com and it redirects to www.mynewsite.com then the component myst be installed on www.mynewsite.com EVEN if the URL has been masked.
otherwise the license willdetect the wrong servername and give the administrator an error.
if you have a subdomain dev.mysite.com which is redirected or accessed by the url www.mynewsite.com then the domain mynewdomain.com MUST be a regisered domain in order for it to be usable. If it weren't registered, then nobody could access it. Including yourself.
