We’re offering a “centralized” css for the odd-wikis
If you like a css with a banner on top for your odd-wiki but you’re not into learning css and experimenting with it too much you can use our "centralized" css. All you have to do is copy it into the css-page of your wiki and substitute the second url with the url for your banner (1280 x 192 px). TheSheep maintains the centralized css. It scales nicely to different screen sizes (on Firefox try “ctr” + “+” or “-”) and even works in the Internet Explorer. 
We’re adapting the titles and some other minor things in the odd-wikis that are using it. The adaption has been finished on the following wikis:
English
French
German
Italian
Norwegian
