How do I get the copy of UBUNTU after donating to UBUNTU?

If you already have Ubuntu installed then you can get the latest apps/softwares by
sudo apt-get install update
typing in the terminal(Ctrl+Alt+T)
If you don't have Ubuntu then follow the steps here to get LTS(Long term support) release of Ubuntu suitable for your needs and h/w by following this link. I suggest Ubuntu Desktop 14.04.3 LTS

After donating there was probably a link to download. If you missed it don't worry, you aren't required to donate.
If you go to the download link from the main website, there's a link on the bottom of the page "Not now, take me to the download ›"
But here are the direct links:
For 64 bit Desktop: http://www.ubuntu.com/download/desktop/thank-you/?version=14.04.3&architecture=amd64
For 32 bit Desktop: http://www.ubuntu.com/download/desktop/thank-you/?version=14.04.3&architecture=i386
