Please update your profile with details of your operating system and machines. That will help fellow users answer your questions. A profile such as "Pages, Lost documents and wasted time." is not helpful.
Please stay with Apple Support Communities. You will see many interesting questions and helpful replies. I have learnt a lot by following these discussions.
