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
Delete All Comments in Word in a Flash
You needn't clear comments in a Word document one by one. Instead, bring out the big guns to delete all of them at once:
1. Chose Tools > Keyboard Shortcuts.
2. Under Categories, select Tools.
3. Under Commands, select DeleteAllCommentsInDoc.
4. With the insertion point in the "Press new keyboard shortcut" field, press keys to create a keyboard shortcut. (I use Control-7)
5. Click the Assign button.
6. Click OK.
You can now press your keyboard shortcut to zap out the comments.
The steps above work in Word 2008; they likely work nearly as described in older versions of Word.
