OK guys thanks for replies.
Since we're talking bout Tikiwiki, I would like to add one thing that for me is weird, why the Simutrans Wiki there's no Simutrans page? I say it cause it's the same search for Wikipedia on Wikipedia and find nothing.
Maybe a XX_Simutrans page for all languages should be added with just some infos about the game like the creator, the versions, the current maintainers and a brief description of the game.
It doesn't need too much information, but only some with links to the specific page with more detailed information.
