I was unable to select the featured article last time, sorry about it. There is a new change taken place, i.e., you should not edit under the "For" and "Against" heading when you nominate an article. You can just comment for it under "Comments" heading. Also, I wished to tell that you need the link the nominated article at the top. At the top you would notice ==Nominated thing <!-- add links with [[name of page|text to display]] -->==, you just need to erase the word Nominated thing and type the link of the article you wish to nominate and do not erase the equals symbols (=), they would make your nominated article as heading. And if the article is already nominated by someone, then you need to edit under the for or against heading and also add comment. Do not forget to put signature at the end of your Comment.
