Apple's Wiki Server Update 1.0 (part of Mac OS X 10.6 Snow Leopard Server) is a minor maintenance update that addresses a handful of general reliability issues. Issues addressed include authenticating users with high-bit characters (such as accent marks) in full user names, enabling wiki group calendar access from iCal, enabling wikis and blogs to remain accessible after a migration from Leopard Server, starting wiki services after a page was modified by a user using their full name, and displaying private blogs that have been accessed by their owner. The update, whose changes are also included in the just-released 1.1 update to Snow Leopard Server 10.6.4 (delta and combo), is available via Software Update and the Apple Support Downloads page.

Fun Way to Send Attachments in Mail
If you're working in a file that you want to attach to a message in Apple Mail, you can transfer the file to Mail easily: From the title bar of the file's window, drag the little proxy icon to Mail's icon on the Dock. Your Mac will make Mail the active application and open a new outgoing message, with the file attached.
(If your icon won't drag, the file probably isn't saved.)
