The A Song of Ice and Fire forum now includes the Tapatalk plugin, which provides greatly improved readability and usability of the forum for users of mobile phones (iPhone, Blackberry, Nokia, and Android-based) who download the Tapatalk app. The plugin comes in a light, free version which allows reading but not posting, and a $2.99 version with posting and other features.
The regular mobile skin is still available, so the Tapatalk plugin is not nor ever will be mandatory for using the forum on a mobile platform.
