I am a Wiki evangelist with more emphasis on promoting access than engagement with editing. For example, making offline (Kiwix) installations available to people without internet. I also try to connect people who can benefit the free knowledge movement with each other. I'm a member of the board of Wikimedia-ZA which is a country chapter with de facto coverage of neighbouring countries.
I've done a dissertation about South Africa's various language Wikipedias and issues surrounding them. See here
