If you're planning on voting in the contest, you need to be a registered forum user. To be a fully registered user, you need to make at least one post on the day you sign up (it's a spam prevention measure). So feel free to make that post here.
And if you're already a forum user, but plan on participating in the contest, feel free to post here too and introduce yourself. If you're submitting a story, feel free to say so, just don't describe it.
