If you are not already at the homepage click the home link now. You should see the following at the top.

Below that should be news. Some news articles, say "view full article". Click there to read the rest of the article. If you want to leave a comment look for the comments? link. (If you are viewing the full article, skip this step.)

After clicking on comments you will have to scroll to the bottom and click on post comment.

You will then be taken to a page to comment. Type in your comment and press preview to preview it. Or you can just press post to post your comment.

Also on the front page there are polls. The current one should be located on the right, and will look something like the following.

Select your answer and press vote. You then will be taken to a page listing all the polls. Feel free to look at them, or just click results to find out the results of them.
