Many thanks to those who posted South African links into the forum. The idea was that you add them to the "links pages" at the link below. I have added those that were posted in this forum but I can't post them all. The idea is that people add a link that they find useful.
Someone asked about a South African search engine, I dont think there is one, directories are not search engines.
This works well:
Go to the Google search add type in what you are looking for
followed by :country code.
For example to find seeds from South African sites type seeds site:.za
Here is a link that might be useful: Links pages
