In case you haven't noticed, I took the plunge and upgraded the site to Community Server 2007.

I have to give props to Telligent for another seamless upgrade.  The upgrade process was easy to follow, and I encountered no errors or unexpected issues.  As far as I can tell, everything seems to be in working order.

My only complaint is that I had to purchase a Personal Edition license due to the number of photo galleries that I host for my family.  The licensing model has been modified to place a restriction on the number of forums, galleries, blogs, and such under the Express Edition.  However, I can understand their business reason for the need to do so.  Besides, as much as I use Community Server, it isn't going to kill me to support the product my buying a $99 license.

I haven't had time to look at everything that has changed.  The most obvious new feature is the new theming engine.  Due to some changes from 2.1, I have lost some of my customizations for my blog theme.  Over the next week or so, I will take a look at the new theme engine and make a few tweaks.  Or, I may just decide to use it as an opportunity to give the site an entirely new look. 

At any rate, I continue to recommend Community Server as an excellent platform.
