Community server removing "www" from your domain name
ObiShawn mentioned on his blog that he was annoyed by the fact that Community Server removes the “www” from your domain name. I completely agree, so I found out how to turn off that behavior. This post is what gave me the answer. Basically, in your CommunityServer.config file, you have to look for the “Core” element and change the “wwwStatus” element to “Require”. It works great on my blog now. You should always see the “www” prefix.
