Changes

:'''Contrary to general opinion, people don't mind having their WIKIs edited''': they may even thank you! This author has created many WIKIs over a two year period. During that time <u>very very few</u> people have taken the time to edit those WIKIs. '''Even if people edit your WIKI, there is a mechanism that records WIKI <u>history</u> (and user name that has contributed to editing change). The ability to see who editing the WIKI "levels the playing field". The WIKI owner can always revert to a previous editing session to restore the WIKI to a previous period...'''
