Guidelines for Composing

Errata The printed guide does not includes a list of where to send submissions since offices tend to change every year or two while the guide is revised approximately every 5 years. The website, however, does include this list here. (Jun/2004 Webmaster)

Subject: [NPL] Solution formats for cryptic crosswords and vowelless forms
To: npl-announce

Dear Krewe:

In answer to a number of recent questions concerning the accepted format of solutions to vowelless forms and cryptic crosswords, I am giving some guidelines. For acrostical enigmas, all types of rebi, and vowelless forms, only the answer is required. However, also giving the partwords for AEs, the readings for rebi, or the expanded words for vowelless forms is never disadvantageous and may, in fact, be advantageous. If your answer is correct but the expansion (partwords, reading, or expanded words) is wrong, the puzzle is still counted as correct. However, if the answer is wrong, then the solution editor has to figure out if the answer might be an acceptable alternate; it's more likely that an answer will be considered acceptable if the solution editor can see your justification.

For cryptic crosswords, all entries (including unclued entries) must be given, either in list form or in a grid. In addition, any extra requirements specified in the puzzle preamble must be given. But when a clue answer is altered before entry, it is not necessary to give the original clue answer or to show or describe the nature of the alteration. This is easier to clarify by looking at some recent cryptic crosswords. For last December's X-3 and X-4, January's X-4 and X-5, February's X-7, and March's X-2, either a completed grid or a list of all entries is sufficient. For April's X-4, however, in addition to giving all the entries, solvers must also identify the puzzle's honoree.

The Guide states that forms must be submitted in the intended shape, not as word lists. However, some find it difficult to make the shapes correctly inan e-mail submission. Therefore, while the intended shape is preferred, I will accept a word list rather than a messy, undecipherable attempt to create the form shape. Also, non-MW words in forms can be incorrect or omitted without penalty. That is, if two non-MW answers cross, the crossing letter can be left blank or can be incorrect and, if everything else is right, the form will still be counted as correct.

In submitting solutions for the new 3-D forms, please include all the individual squares or whatever shapes, even if they repeat words. It is much easier for me to see where you are in the puzzle that way. (added Apr 9/2007/webmaster)

I trust the above will be helpful. If there are any further questions, let me know at my usual address.

The League unanimously elected to amend the bylaws as proposed at the 2006 Convention. From the Oct/2006 Enigma:


The following bylaws amendment (with minor changes in wording) was authorized by the business meeting at the 2006 convention for placement on the fall ballot. It has two principal functions.

Errata CURRENT BYLAW 4: A business meeting shall be held each summer at the annual convention. The order of business at the meeting shall be as follows: reading of the minutes of the previous meeting; reading of the names of members who have died since the previous meeting, and a moment of silence in their honor; reports from the treasurer, and from other officers, individuals, and committees, as appropriate; unfinished business; new business, including presentation of offers to host the following summer's convention, and election of the same; miscellaneous announcements; adjournment.

PROPOSED REPLACEMENT: “new business, including presentation of offers to host future conventions, and election of the same;”

Errata CURRENT BYLAW 6(A): A convention of the membership shall be held each summer. The sites of future conventions shall be decided at the annual business meetings, and a business meeting shall not be adjourned if no site for the following year's convention has been elected, unless the assembly has authorized, by majority vote, a committee to select the site at a later date.

PROPOSED REPLACEMENT: “and a business meeting shall not be adjourned if sites have not been elected for both of the two subsequent years' conventions, unless the assembly has authorized, by majority vote, a committee to select the site(s) at a later date.”

Errata CURRENT BYLAW 6(B): At a business meeting, any member may present to the assembly an offer to host a future convention. When all offers have been presented, and after appropriate debate, the assembly shall vote, and the offer receiving the plurality of votes shall be elected.

PROPOSED REPLACEMENT: “When all offers for a particular year's convention have been presented, and after appropriate debate, a motion may be entertained to vote to select a convention site from among the offers presented.”
