The Help tab located in the Main Menu has a lot of similarities with this As a regular user section of the Wiki. The difference is that users can access the help pages from within the forum itself, rather than coming to this wiki. The help pages contain a lot of handy guidance and instructions about getting around SMF and using its features.
In SMF version 2.0, the Help tab of the main menu directs users to this online documentation at SimpleMachines.org. The wiki is in the process of being updated to reflect the changes in SMF 2.0, and will continue to help new users understand how to use the features of SMF.
