The Community Server is members only area.
Community Server is very simple to use. It now includes browser-based tools to make changing page layout, selecting fonts and font sizes, site colors, and images unbelievably simple.
For designers and non-technical people these tools will enable Community Server to look however you want without requiring any knowledge of HTML, CSS, or .NET. If you're a .NET developer we've done a lot for you too. You'll find simpler and cleaner organization of code and files. We're almost ashamed to admit it, but in Community Server 2.1 there were nearly 55 files for a blog theme. But we're proud that in Community Server 2007 a blog theme has only 8 files!
Below you'll find some helpful information for evaluating Community Server 2007 and don't forget to visit www.communityserver.org -- the "community" for Community Server.
