I have used this extension for creating a resource library section. Very easy to install and extensible. I had to do some minor (customer-requested) template changes which require some hacking and reading on the Mosets forums, but the code is very clean and the change was very easy to do. Will be using it on my future projects.
Wow, this is a very complete extension.
Even better, after trying several other extensions this one sticks out on top of all others.
I had it up an running in Joomla in just a few minutes.
I recommend this extension !
