Hey Chad,

That's a pretty general site you're pointing to.

Could you possibly be a bit more specific? Clicked through a couple of
links on it but everything was very high level.

As I noted elsewhere I am in SA but my employer is national so keeping
across all this is never a bad thing.

Cheers,

Sam
