i know its a stupid question but still .. .. can i really host 6 different domains with one Advanced hosting($60)? .. how do i add other domains? i tried, but nothing happened..
You can host 6 domains total if you purchased the Advanced Hosting without any upgrades.
The first thing you need to do is change the Name Servers for your domains to ns100.dynadot.com and ns101.dynadot.com.
Once you do that, wait about 10-15 minutes for the DNS changes to take effect. Then, log into CPanel and look for the "Add On Domains" Icon and click on it. You'd fill out the page shown here.
When you upload files for that particular added domain, you'd add them directly into the folder that was created for that folder.
