Tom, you probably know this and just mistyped, but guest accounts aren't new to Snow Leopard. Leopard has guest account functionality too. The bug seems to be new to Snow Leopard though.
From: Tom Piwowar <t...@tjpa.com> Not to be outdone by M$, Apple has got its own catastrophic bug... "Snow Leopard's home directory -- the one sporting the name of the Mac's primary user -- is replaced with a new, empty copy after users log-in to a Guest account, log out, then log-in to their standard account. All the standard folders -- Documents, Downloads, Music, Picture and others -- are empty, while the Desktop and Dock have reverted to an "out-of-box" condition." http://www.computerworld.com/s/article/9139250/Snow_Leopard_bug_deletes_all_user_data This Guest Account function is a new Snow Leopard feature. It lets someone log into a Mac as a temporary user and when their business is done and they logout, all traces of their session are deleted. It looks like Snow Leopard is deleting far more than Apple intended.
