At one point 2 years ago, Douglas Richter at Cybersocket was handling our account. We (Sebastian Sloane Productions) had received a nomination. When Morgan had us all up in his world and was all goody goody two faced with us he really expressed an interest in us within the CS Awards.
We really thought it was a cool ass thing.
Back to Douglas, I asked how does one get started to possibly winning an award? He said, "You place the CS banner on your site. You request the public, members, website visitors, etc. to click on the banner and vote for you." The banner was never placed on the site. We too had been nominated.
Nothing ever came of it.
So, what I understand is the only way to be nominated is by requesting that your users to vote for you. Just my $0.02
