Ok I had a few issues finally making the domain mapping plugin work. I had to make sure I had the GoDaddy domains parked on my hostgator cpanel park domains under the main domain. Once I did this, they all showed up.
I did have an issue with one of the domains mapping. I did not set up the proper A record first before mapping and I kept getting errors. I finally deleted site from mapping plugin and set up another subdomain and then mapped with the A record correct. That worked.
Overall not to bad yet. Of course I have not pounded away at it yet. I did get the All in One SEO pack to load via the network domain and a Google Sitemap for multisite to work. I did put one domain into Webmaster tools and it worked ok. Need to do them all this week and start writing some articles to give each at least 25 to 50 pages to index before we can see if this really works like I hope.
