Continuing the discussion from [18 July] What are you working on this week?:
A quick clarifying question: I believe your community is focused on encouraging E.Africans to learn and use technology, is that correct?
What are their core values? i.e. What are they motivated by? Members are most likely to create content if they feel that content will go some way to satisfying that motivation (e.g. it will help others advance/ be more independent/ demonstrate obedience?)
There is a section in this guide (see pg 35) about stimulating user generated content.
