Learning to share is a very important aspect of learning. Posting your reflections for everyone to learn from during a workshop is very important. Connecting with the facilitators to add your feedback limits the scope and lessons learned to 1 or 2 people. If you missed a few sessions of a class and wish to continue collaborating, which I encourage everyone to do, please add your thoughts on a blog and share it with the world. This way you don't limit your audience and everyone benefits. However, don't forget to share the link with the class participants so they can learn and respond.
