Hello
I did a bigger Wiki cleanup today. I inserted a category tree and tried to fiddle all existing pages into it, then I tried to organize page names in categories more consistenty. Reorganization of the main page. I got rid of the Miscellaneous chapter and added a Development chapter.
I also started a contribution guidelines page [1], please refer in the future to it.
So I hope you don't get too confused with all the changes and apologize for any confusion this reorganization may induce.
