This part of their policy is almost funny seeing how much we all just "love" WP:TLAs
"No initialisms. The Policy pages of the Citizendium may not contain any three-letter "initialisms." For example, "IAR," "NOR," and "AFD" are three letter initialisms. These expressions are a considerable problem for new users who are unfamiliar with them. The first time a user introduces such an expression in a policy page, he/she will be warned and the expression removed. The second time a user repeats this offense, he will be banned for a suitable amount of time.?
