1) Books must be released during the period from December 1 to December 31. No need to sign up - join in at any time!
People who *have* signed up so far:
2) The challenge is to release books that have a the letter "D" beginning a word in the main title OR the author's name.
* Dean Koontz, John D. Rockfeller, and Charles Dickens will all count. Scott O'Dell won't, sorry.
* Main title means anything before the colon but not afterwards. For example, _Ice Bound: A Doctor's Incredible Battle For Survival at the South Pole_ and _Stolen Lives: Twenty Years in a Desert Jail_ wouldn't count. Series names don't count unless they're part of the actual book title, so _Tea Time for the Traditionally Built_, while part of the No. 1 Ladies' Dectective Agency Series, wouldn't count..but the first book in the series is actually *titled* _The No. 1 Ladies' Detective Agency_ so it would be fine.
3) Any type of release counts: wild releases, charity releases, controlled releases, books left at OBCZs or Little Free Libraries, sent out as rings/rays, books in bookboxes, etc.
4) Nouns, verbs, adjectives, adverbs and proper nouns in any language count
* Only the first letter of an acronym/initialism counts- as in D.A.R.E. but not M.A.D.D.
* Articles don't count- - for instance, if the word "the" begins with the letter D in your language, it doesn't qualify. (Besides, you should release those for the "The" challenge during November!)
* If your language doesn't use the same sort of characters as English, it should be a word that begins with the same sound as the letter D in English (in other words, it would be transliterated into a D in for English speakers). I'll have to take your word for it at least 99 and 44/100% of the time, so please play fair! ;)
5) One point per book, regardless of how many D words are in the title. So _Darkness Before Dawn _ and _Double or Die_ only count once each!
6) Multi-challenge releases are perfectly fine, and even encouraged (because they're more fun).
7) There will be a few small prizes, probably for random participants.
If you have questions, just ask. :)
