If it is not already done, I think it would be a good idea to give joiners an "short information pack" of useful information when they sign up. It does not have to be much - say something like:
As a new user you will find much useful information in the Writer FAQ, the Writer Tutorials, the up to date Writer guide and the OOo v3.3 Writer Manual. When a pop-up window opens, click the Help button for extensive help on that function - it is often more comprehensive than the manual.
Also, please always search the forum before posting a query as the same questions get asked again and again and again and again ...
