wauhhh...it's glad to hear that you really plan to come in Africa. The steemit community has been growing and we are glad that atleast in Uganda we have been able to have more than 300 steemians. Well, we still need more efforts to reach as higher as we can.
I was also able to start a steemit community in Rwanda and I'm really planning to strenghening it after my studies in Uganda offwhich I live and do numerous activity with a good number of steeians.
Ibelieve that South Africa will also have a good number of steemians as Nigeria and I really believe in the potential and technology advancement available in South Africa.
Cheers.
