Thanks for the quick response, KazVee! Much appreciated.
If I'm not mistaken, what I want to accomplish (see above) requires addon domains and not subdomains. I want to point a domain that I already own (say, my-domain.com) to a folder on HelioHost. If I understand the documentation correctly, that would be my-account.helioho.st/my-domain.helioho.st/. Then, after modifying the nameservers for my-domain.com, you should see whatever is in the my-account.helioho.st/my-domain.helioho.st/ folder. If that's correct, can you please add these addon domains to my account (ronvdc):
ronvdc
rvdc
dutchoutpost
biljum
tiffanybiljumtherapy
adventuresintech
Or is there a way to accomplish what I want by simply putting the content for each site in subfolders on HelioHost (so, for example, ronvdc.helioho.st/dutchoutpost) and then updating the nameservers for dutchoutpost.com to open the contents of that folder?
Thanks!
