I don't know why, but I can't post comments on the "News & Updates" section of the web. When I use Mozilla it says like it's a kind of error, and if I use Internet Explorer I can't see the secutrity image... Do you have problems too? Or it's only me?
"People make up explanations... assign meaning to things without knowing, because it's reassuring. It's comforting. But I can't do that... because I know too much." Olivia Dunham
I just tried it and it works for me. Sometimes the letters can be unclear so you have to look closely, and if you get them wrong and them hit the back button to try to submit again you'll need to refresh the page for new letters to be displayed.
Try that and let me know if you have any success...
