It's done!
Thanks to everyone, specially Frank.
Old post:
WARNING! 
don't get confused with current wiki (TikiWiki) update, see the relevant topic
here. This topic is about the ancient wiki (MediaWiki --
this) that was shut down years ago and
might have some pages left behind.
Stepping forward!
I'm opening this topic with purpose of helping people who is interested in improving our on-line manuals to port the wiki texts from old wikies to Simutrans-Germany Wiki.
If you have any trouble or need to say something, post in this topic.
Instructions:1) Open any wiki text of the following old wikies:
http://en.wiki.simutrans.comhttp://es.wiki.simutrans.comhttp://it.wiki.simutrans.comhttp://pt.wiki.simutrans.comhttp://fr.wiki.simutrans.com2) Search for corresponding wiki text on Simutrans-Germany Wiki, on your language:
http://wiki.simutrans-germany.com3) If:
-- the corresponding wiki text exists: compare both texts and complete Simutrans-Germany Wiki text.
-- the corresponding wiki text does not exist: copy the text from old wiki and create a new wiki text on Simutrans-Germany Wiki with proper format.
4) After you have successfully transferred the text, blank the old page and put a note warning that text was transferred. A sample of a successful port:
http://en.wiki.simutrans.com/index.php/Traffic_congestion_control-- if you don't have an account on the old wiki, you can ask here for someone to blank the page for you.
5) Post here informing us the pages that were transferred.
