Apple Drops PowerTalk Until Copland -- According to MacWEEK, Apple has confirmed it will be moving away from PowerTalk as its core communications solution until the next major revision of the Mac OS is available, citing very low adoption by users and developers. PowerTalk 1.1 will ship this quarter, but won't re-appear until a wholly-rewritten version based on OpenDoc and Internet technologies (like Glenn Anderson's Apple Internet Mail Server) ships with Copland.

Turn Off Filename Extension Warning
In Leopard, Apple fixed an annoying aspect of working with the Finder in Tiger. Previously, if you changed a file's extension, the Finder prompted for confirmation. But since no one has ever accidentally changed a filename extension, Apple thankfully added an option to turn that warning off in the Leopard Finder's preferences. Choose Finder > Preferences, and in the Advanced screen, deselect Show Warning Before Changing an Extension.
