I have been using FLEXicontent now for quite some time now, so I guess that my review is long overdue here. Nonetheless, I wanted to make sure I gave one.
At any rate, product is phenomenal and it truly changes the way that a Joomla! webmaster deals with categories and articles on a daily basis. FLEXIcontent works with several other extentions and the number of options it has these days for both an experienced and novice user makes it a work of art. As other extentions update and change, so does FLEXIcontent to maintain its working order. In fact, it has so many positive point about it, I will never get to all of them in this post.
However, you must know that the excellence does not stop here. The FLEXIcontent team meets and exceeds expecations by solving countless customization issues within the forum area. For example, I had an issue a few weeks ago and ggppdk (Lead Developer) went into my website for me and found the problem. He immediately coded a fix and implemented the fix within the next release. In fact, it appears that he does this for people on a regular basis. He is definitely a busy man! The rest of the team also takes the time necessary to help people with customized solutions. I could not ask for more.
In a nutshell, if you are looking for a Class-A extention and category/article management system, and more, with a dedicated development team behind it, then FLEXIcontent is the one for you. Try it and you will see.
