We worked with the support team at RealNetworks to redesign and rebuild their knowledge base / customer support sites. In the original project, we created five KB sites, for: RealPlayer, Subscriptions from Real / SuperPass, RealArcade, GameHouse and Rhapsody. (Note: RealNetwork's ownership in some of these products / sites has changed since we originally worked on the KBs.)
For the GameHouse support site, we were given the task of designing and developing a feature-set that very closely matched what we had done for the other KB sites, but that was 100% compatible with the look and feel of the GameHouse website.
In addition to adapting our information architecture and layout work to fit within the GameHouse site structure, we also integrated the KB code with HTML compatible with the GameHouse stylesheets.
