Apple is no longer restricting Mac OS X betas to paying developers. Anyone with an Apple ID (which is, let’s face it, essentially every Apple user at this point) can now sign up for the OS X Beta Seed Program to test unreleased versions of the operating system. You have to agree to Apple’s OS X Beta Seed and Confidentiality Agreement and install the Beta Access Utility to view betas in the Mac App Store. After WWDC, we’ll see if this applies to major releases of OS X, or just minor updates.follow link
Adding Links in Snow Leopard's Mail
Apple Mail in Snow Leopard now has a Command-key shortcut for adding a link to an email.
If you use plain-text email, this will not be helpful at all, but if you send styled email, it's a nice shortcut for adding URLs to your email messages. Simply select the word(s) you want to make into a link, press Command-K, and enter the URL to build into the link.
