Blonde needs help ...where's the blog icon?
If you want to create a new thread on any board, you do it the same way you did here -- go to the main page for the appropriate board (there's a list of them all on the front page at http://www.chowhound.com , or use the arrow next to the word boards for a quick list) and choose the 'Add a new topic' button to add you post.
If you want to reply to an existing topic, there should be a 'reply' link on each post.
Does that help? If not, let me know and I'll try again.
