Just in case anyone is interested we have a Jozi Linux User Group up and running that meets once a month in Randburg, Johannesburg, usually Bright Water Commons at Scrooges Diner. We get about 10-12 people at each meetup and growing .
If anyone is keen to give a talk or presentation at the meetup please let us know. (Obviously no marketing stuff just FOSS.) You don't need to be an expert to attend just keen on learning more and helping build a community More info can be found at:
We also planning to participate in Software Freedom Day this year in September and there are people keen to help roll out computer labs at schools, so that is in the process of being organised.
