This is such an important component, I don't know why it wasn't native to Joomla from 1.0 - it is to wordpress. I have waited 5 yrs for this, nonetheless, it works well for me, very concerned about the forum, support and whether the project will continue, I think it is a lucrative component if marketed well. For me, it is essential for our website. We must be able to use multiple categories and I assume thousands of others too. A must have if you have many article items and authors.
We agree that this component is necessary. We also have committed to upping the support for components. To that end we have created new forums (free of spam) and I have been put in charge of all component support. If you need anything further please don't hesitate to contact me at firstname.lastname@example.org.
I welcome your feedback!
