When you have got a prompt that needs answering, you'll see a linked called 'Prompts' appear in the left hand side of the utility bar in your blog. It may say something like 'Prompts (2 + 1 new)' which would indicate that you have two prompts to answer which are outstanding and one new prompt. If you click on the link, you'll be able to see a list of all the prompts which you need to answer, plus prompts that you have already answered, and prompts that have expired. You can answer or discard a prompt and you can also see answers to other prompts that are publicly viewable. When you answer a prompt, it will create a specific type of entry in your blog.
