Fellow MVP Maurice de Beijer recently launched a Wiki-based website on Windows Workflow Foundation (WF). Although I sometimes find wikis difficult to navigate, Maurice has managed to publish a significant amount of information. Here's a short list:

• Tracing Workflow Foundation
• Spawned Contexts
• Designing Your Workflows
• Workflow Inconsistencies
• User Track Point
• Replicator Activity
• Workflow Samples

A wiki is all about joint content sharing, so if you've found some good resources on WF or are currently involved in a WF project, please share!
