ABOUT THE PROJECT
The XWiki Store is a collection of payed extensions that can be installed on top of the platform. The key principle behind the proposal was to create a design easily scalable and customizable, while allowing each extension to have an individual marketing strategy. XWiki is an extensible open source platform for developing collaborative applications on top of the wiki paradigm.
I prefer to interact and create the design in the environment it will live in, so I usually code my prototypes directly in HTML+CSS.
