The FAQ's on the Dynamics User Group are your pages. You ask the questions and the answers.
If there's an article/page which you think is wrong, then please just go ahead and edit the article/page (just click on the Edit tab - if you're logged in). Or if you don't want to edit the page, then you can just write a comment.
In many pages there are links to new pages that still needs to be created. You are very welcome to go ahead and start the page, with the information you think the page should contain.
And don't worry if it doesn't look perfect or if you make spelling errors because your English is not perfect. Another member will then be able to fix the article.
The FAQ is just like the Wikipedia's you know from other sites and is like that a work-in-progress that will never finish.
