As a general rule, jargon should not be used without being explained. This might be somewhat complicated in the context of Nupedia as a whole, because, very likely, the item of jargon will have its own entry, however brief. Hence some care must be taken to ensure that the gloss given of a bit of jargon squares with any "official account" already given in Nupedia. Explanation of jargon could (and no doubt will) be handled, in the future, using special cross-references (in which clicking on or hovering the mouse over a word will cause its definition to pop up); but until some such system has been perfected, the rule will be that all jargon should be explained within an article itself. This rule can be relaxed with regard to basic jargon within very advanced/specialized material that a lay audience could not be expected to understand in any case.
