Levels of participation in a community of practice

Wenger-Trayner notes [here] how there are different levels of participation within a community of practice. This is visually represented very nicely below:

This serves to reaffirm my view of 'The Positive Psychology People' (PPP) as the basis for a community of practice, as this reflects the 'structure' (if that is the right word?) of the levels of participation in the PPP, with there being a core team of co-ordinators, a wider group of active 'members' (e.g., developing content for the web resources), and so on.

Using this as a framework, I can see MAPP students becoming initially involved at the 'peripheral' level and, depending on their own interests, becoming occasional or active contributors to discussions and other activities.
