Microsoft has developed the Productivity Hub to help support your ongoing end user training efforts. The Hub is a SharePoint Server site collection that serves as a learning community and is fully customizable. It provides a central place for your training efforts, and includes training content from Microsoft’s core products. Microsoft also provides ongoing and updated content packs. The Productivity Hub is a Microsoft SharePoint Server 2010 site collection that offers training materials for end-users.
The Hub uses SharePoint Server’s social networking capabilities, such as blogs and discussion groups. In addition, it offers the Coach program, a change management feature to help you train end users to self-help, reducing the burden on your training and IT staff. The Coach program impacts productivity in a collaborative and positive way. The 2010 version of the Productivity Hub includes a quiz feature, a section called ‘Get it Done’ that offers training for tasks such as email management and collaboration, and also features Silverlight. There will be a non-Silverlight version of the 2010 Hub delivered in late June. The 2007 Hub contains 2007 content only (v2) with 2010 content added in v3 (to be released in June 2010). You can also add 2010 content packages to your current Hub. Watch for more document on migration from your 2007 Hub to your 2010 Hub. What the Productivity Hub is:
You can also download additional content packages that expand the training materials you can make available through the Hub.

Where is there information on managing Productivity Hub - e.g adding proprietary pages, either for additional products or for internal information on standards and governance practices? How are any such "customizations" handled when downloading SPs?
