However, after using it for any length of time, you'll quickly discover that it's half baked, poorly thought out and, in many cases, buggy.
A classic situation is that very basic functionality works well, but more advanced features either don't work or require you to organise your Joomla installation in a very specific way for the component to work correctly.
Support is minimal to non-existent, relying on a community forum where many requests for assistance are either ignored or treated with derision.
In summary - if you are prepared to spend time messing around in PHP to make this component work, go for it.
If you want something to install and simply work, I'd look elsewhere.
