This may raise some hackles. Although there is always room for improvement, it can be argued that MediaWiki *is* a good design for what it was designed for! It's just that limiting visibility was not and is not important to the designers. One should not design for things that are not specified nor desired. That would be a bad design! :-) Gotta go now and put a sail on my Porche. I just can't believe those arrogant German engineers, making it so hard to attach a sail to their car! Must be poor design... I agree with several here who said that two or more wikis is the way to go. When the page gets mature enough to share, a simple export/ import script can make these perfected words of wisdom available to the unwashed masses. Good designs for anarchy and consensus tend to make poor designs for hierarchy and control. :::: Political language -- and with variations this is true of all political parties, from Conservatives to Anarchists -- is designed to make lies sound truthful and murder respectable, and to give an appearance of solidity to pure wind. -- George Orwell :::: :::: Jan Steinman http://www.EcoReality.org ::::
