Refer to the list of membership communities researched above. 
And to my own 3 level community structure. 

1. Find gaps in the market that my community fills. Provide a list. 
2. Find gaps in my course that other many other communities fill that I do not. Provide a list. 
3. Adjust my community structure with both 1 and 2 in mind to improve its position in the market.
