[ubuntu-za] Where to download the Ubuntu Natty Narwhal for our launch party

[Nick Michael(PtaISP)]

Hi there

I am trying to download the Ubuntu Natty Narwhal for our launch party
I found this URL :
http://cdimage.ubuntu.com/releases/natty/release/

Is this the correct URL for the latest release  of Natty Narwhal ? The one  needed for the launch party?

as I only found a Beta version on the SAIX site

Please advise

regards
Nick
