HTML http://www.acm.org/crossroads/submit Between 1500 to 6000 words for a feature article, and
800 to 3000 words for an opinion column.
In the beginning of your article, tell the reader—in a captivating way—what your article is all about. Be sure to place your article into a broader context. Remember, our audience is composed of informed, multidisciplinary students. Readers must first learn the context of your subject before they can understand how your work changes the field or affects their decision making process. Anecdotes are entirely appropriate.
Acronyms do not take articles. Active voice replaces passive voice whenever possible. Systems, programs, commands, routines, and so on, however, appear in small capital letters. Use he/she, not he or she alone. If possible, rewrite sentence to use 'they'. Use the singular pronoun I (not we) for a singular author. Use that in restrictive clauses (those without a comma) and which in nonrestrictive clauses (those with a comma). Use while to mean "at the same time" and although to mean "in spite of the fact."
