One of the more exciting new releases for Joomla 1.5 recently has been K2 from Joomlaworks.
K2 is a content construction component, which lets you create custom content types (items) for your Joomla! website. With K2, build all sorts of different types of page: news, blogs, product catalogs, work portfolio, knowledge base, download/document manager, directory listing, event listing etc.
I thought I wold take k2 for a spin in a "raw" video review. I installed K2 and put it through its paces without ever having used it before. Raw look, no reading documentation, just install it and play!
