An extension in Joomla must be solid. These is a Beta. So, it's not recommended for live sites like mine. I really love the upgrade wich have these extension. I had issues with other versions, and finally i use Filezilla. It's a good component? Sure, it WILL be, but: no forum por bugs, when users can interactuate between them, if i want to report that i have a blank page now when i try to access component i must register in repository. If a component don't have a good documentation -it hasn't- and a forum, well, it's 2011, but can't give a 4 o 5 stars because it's an incomplete product. The development is STILL in beta. I think when it became a solid component it will be integrated in Joomla, but now... I'll wait for next upgrade, maybe final release.
