Being MyBroadband's oldest member (check my profile, it's true), I remember what all your towns looked like. Well, if you come from Joburg, East london, Durban or Cape Town anyway.
I've made a habit of collecting old photos of various places while I've been wandering around the internet. I'm slowly building up my collection and they're all backed up across various sites so that they don't get lost anywhere.

There's stuff for Joburg, Cape Town, East London and Durban - unfortunately still very much unorganised but I'll get there one day
If anyone knows of any other places I can get my hands on some of the old stuff, please let me know. I'll upload the rest of my collection in time
