The (unofficial) gallery of Windows Media Center applications, MadeForMediaCenter.com is like an app store just for Media Center users. Now that gallery is available as a Media Center addin so you can download new apps to Media Center without having to leave the Media Center user interface.
To get started, you’ll first need to create an account at MadeForMediaCenter.com, then download either the 32-bit or 64-bit version of the addin. Once installed, the addin will prompt you for your credentials upon first launch. After entering in your info (username and password), you can browse the available third-party media center apps and install them immediately.
Also, may I just say this to the developers: thank you for this awesome project!
