DanGates, the 10-domains plan is all in the same filespace (/www), under the same root domain. It's just a trick of the web server's configuration that makes it look like distinct domains to users (but it's completely transparent to them, no worries).
Meaning you have
rootdomain.com, you want to add
domain1.com as an addon domain. You do it through the cPanel with a password and username/subdomain/subfolder (same for all 3).
What really happens is: domain1.com gets added as a subdomain of rootdomain.com, meaning you can access it as domain1.subdomain.com.
It's documents will be in a subfolder of rootdomain.com, meaning:
/www/index.html -> index for rootdomain.com
/www/domain1/index.html -> index for domain1.com
You can access domain1.com with:
http://domain1.rootdomain.com/index.html or
http://rootdomain.com/domain1/index.htmlHowever, the web server and DNS configuration makes it so that you can
also access domain1.com as you intended (as a distinct domain), meaning
http://domain1.comBut all it's files are still in a subdirectory of rootdomain.com and you will always be able to access it through the other addresses above (although javascript or PHP can also fix that so that your users must access it through the distinct address and don't get mixed up in subdomains).
Ok, now if you've followed me through all this, the following points are important:
1. It's meaningless to have Frontpage (or any program to transfer files) point to a subdomain, since it's all under the root domain. You can actually set Dreamweaver or other HTML editors to accept the correct subdir as root dir for that site, but Frontpage has server-side components that preclude this trick, because server-side it's all the same filespace.
2. It's the same for a bunch of other features: Index Manager doesn't work on subdomains, because as far as files are concerned it's all subdirectories so to lock the index of the rootdir of a subdomain, you lock that subdirectory in your filespace. All your SQL tables are in the same place and are visible throughout all your 10 domains.
3. If you erase the domain1.rootdomain.com subdomain that's auto-created by cPanel when you create your addon domain, things will go horribly wrong, because it will break the magic.
4. All the features that really need to work with subdomains, do: email, mailing lists, ftp.. all are configurable per subdomain.
Hope that helps. Don't thank me, I'm just trying to free up the staff so they can work on the reverse-DNS problem with server17
