I got my coordinator and "met" her via e-mail. She sent me a 55 page information book filled with all the information I'll need. I also paid my program fee (I paid my registration fee when I accepted the placement) which means it's official. I'M GOING TO SOUTH AFRICA!
I also think I've found a way to save on the flights by booking first to London and then from there to Cape Town. This seems to be cheaper than trying to get directly from here to there. Right now I'm trying to make the timing work to see if I'll need to overnight it London.
I'm in awe of how quickly things are happening!
