Template:PD Help Page You can obtain a copy of the help system in this wiki for local use in your own wiki following these steps:
Help:Contents Help:Navigation Help:Searching Help:Tracking_changes Help:Editing_pages Help:Starting_a_new_page Help:Formatting Help:Links Help:Categories Help:Images Help:Templates Help:Tables Help:Variables Help:Managing_files Help:Preferences Help:Skins Help:Namespaces Help:Interwiki_linking Help:Special pages Template:PD_Help_Page Template:Meta Template:Mediawiki Template:Admin_tip Template:Prettytable Template:Hl2 Template:Hl3 Template:Thankyou Image:Example.jpg Image:Geographylogo.png
Sysops only:
Template:Click Template:Languages Template:Languages/Lang
For the images this only copies the image descriptions. You need also to upload them on your wiki. Although not complete, at least this gets you started on a decent help system.
If you use pywikipedia, there is a script to automate the copying at http://mediawiki-tools.cvs.sourceforge.net/mediawiki-tools/pywikipedia/mirrorhelp.py, which copies all pages in the help namespace along with templates and images directly referenced by those.
