I currently have a website hosted with Hostgator and am using Soholaunch Sitebuilder to create and manage the site. I can add unlimited addon domains. I thought I could use Soholaunch for those sites as well, but it appears that all the "sitebuilders" they offer only work to build the MAIN domain.

So now I need to figure out how best to build my other sites. I've been told I could use Wordpress or Joomla or other options though Cpanel/Fantastico. But I really don't want to learn to use one, only to find that I need to learn another one to build the other sites...

What I'm looking for is a reccomendation for an easy to use sitebuilder that I can use to create multiple sites. I've heard talk of CMS, not sure if that's something I need. At least one of my other sites will be an "ecommerce" site in case that makes a difference. I plan on using paypal type buy-it-now buttons or a shopping cart, not sure yet.

I'm familiar with Frontpage, but I didn't really like using it. Any reccomendations or suggestions would be great. Thank you.
