For beginners it's quiet hard to find specific guidelines or help pages. Newbies don't even know that such pages exist. Context specific advices would be a possible solution for this problem.
It would be very helpful to get an editintro in user defined sections.
The page 'MediaWiki:SectionHelp' contains:
- External Links|Template:Help on external Links
- References|Template:Help on References
- Source|Template:Help on adding source information
When someone tries to edit the section 'External Links' the 'Template:Help on external Links' is shown at the top of the edit-page. The information (template) shouldn't disappear in preview mode.
