No, I think it should be even longer, maybe a paragraph or two, because the concept of "A-list" versus "everything else" is just too complex and unfamiliar to express concisely. What's wrong with "other" or "additional" in contrast to "recommended" or "preferred"? Or is the intent really to say "don't use these"? -- Doug Ewell | Thornton, CO, US | ewellic.org
