I do see the DreamHost Coming Soon page! That means the DNS is all done propagating. If you don’t see it, There may be a local cache in your browser or computer, and you can try clearing local caches with instructions from our wiki pages http://wiki.dreamhost.com/Clear_cache and http://wiki.dreamhost.com/Flush_DNS. You can usually view your site soonest from a non-caching web proxy such as anonymouse.org. Just enter your domain there and view the site exactly as it is on our servers, with no caching or outdated info.
Once you see the Coming Soon page, you can follow the “helpful links for getting started” links to help you start building your web site. Have fun!
