Forgiven for the Microsoft thing. :-)
As for restrictions in the free version, there are honestly very few. It's the Express Version column on the
Product Features page. You can see for yourself what may be unavailable or restricted. The only real restriction is that the file gallery is limited to 50 files. The RSS Reader isn't really used much anymore (it's like a client feed reader on the server) so its restriction has little affect. The files limitation can be an issue though.
With the Standard License or above you can use (buy :-) the add-ons that make Community Server quite unparalleled as a community platform, IMO.
Another point that may or may not be of use to you is that all of the source code is available in the Express version if you download the SDK. With the source code you can customize it if you don't like it.
There isn't a free trial of the Hosted Version, but it's the very same application as the free (express) version of Community Server, just that it's already setup, hosted and maintained for you.
Another thing is that the community site of CS (
communityserver.org) is the actual application itself. Everything you see at cs.org is what Community Server does. The same bits at cs.org go into the express version and every other version of Community Server.
I'm going long here, very sorry. Best advice is if you have a Windows IIS web server and database somewhere (or any $9.95 a month host account) you might want to download the free Express version of Community Server -
the Web Installer version of CS 2.1. That's the easiest to install. If you have problems, ping me personally at davebu @ telligent.com and I'll be happy to help you.
Thanks,
