The software has good logical layout for the backend and is extremely easy to setup. It's well worth purchasing the "Documentation" package not only for the well written User Guide but also the access to powerful extra plugins.
As an administrator you can set the display options for the plugins to make it look similar to a Facebook account or have everything under "tabs". I personally prefer the tabs approach as it keeps the profile page nice and clean.
My only negative is that the forum / calender being supported both need to run in "legacy" mode but that said I have seen no issues turning legacy mode on and the forum software (Fireboard) integrates perfectly. (I did ask about this and the issue is being addressed, hopefully soon I'll be able to go back to pure native mode).
So, in short, this package has everything you need to build a community. The forums are active and my questions where answered incredibly promptly.
