I want to translate a word in my app. First I wanted to use Google Translate but I saw Google Translate's API is not free. So I tried to use Bing Translator, I followed this [tutorial](http://www.microsoft.com/web/post/using-the-free-bing-translation-apis), but in step 3 I can't find "*Get started by applying for an AppId now*". So how can I create an appID?
