You can nominate if you choose by posting in the appropriate category. All posts and threads go through moderation so you won't see your post right away. This way I won't miss one. I will record each nomination in the first post of each category. In January (2013) we will start the full process of nominating and February voting for the 2012 year.
In your post please provide a link to appropriate post/thread. You can do that by finding the post you want (post of the year) and hitting reply with quote. Then copying and pasting that quote in to the nomination thread. Same as with thread of the year. Find the thread and hit reply with quote for the first post of that thread and copy and paste the text in to the thread of the year category.
If the nomination is for a poster (example: poster of the year) I just need there name.
reply with quote example: The little arrow icon next to the name is a link to the post.
