Nominations[edit]

More "Did you know"s can be nominated here. General guidelines for nominations, loosely based on Wikipedia:Did you know include:

  • Pick DYKs in articles that are interesting.
  • Look for articles that are over 1,000 characters in size - no stubs.
  • The "Did you know?" fact must be mentioned in the article.
  • Try to select articles that cite their sources, particularly the item mentioned.
