  • Sorry Snood1205, but it's not eligible. There's been no recent expansion and it's not a good article. (Plus the nomination hasn't been transcluded to WP:DYKN.) If you expand the prose five times, or get it designated a good article, you may resubmit within a week of that happening. Please see WP:DYK for more information.
