Intel have been pretty quick off the mark at getting their Tizen application developer forum for AppUp setup. I can only hope they are this quick with the SDK (Hint Hint).
Welcome to the Tizen application developer forum for AppUp. Post questions or engage in discussion regarding Tizen, a new Linux open source cross device platform with support from Intel AppUp developer program, and a development framework based on HTML5 & WAC standards. Tizen will support multiple device categories, such as smartphones, tablets, smart TVs, netbooks, and in-vehicle infotainment devices . The Linux Foundation hosts the project, led by a technical steering team composed of Intel and Samsung.
