Registering a new user

Hi there

I live in South Africa, when I tried to register it kept on asking for a valid postal code or zip code, or type in N/A

I tried N/A and that did not work, the error kept on poping up, I tried 0157 (our country only uses digits) that did not work.

Finally I chose Zimbabwe as my country and N/A and then all was fine and registered...

Maybe the error message might be changed to be more helpful or make sure that "blank" or N/A does actually work for South Africa
