Wikispaces created a new default wiki style a while ago and we think about giving our wiki a new style as well, but we want you to choose which style you prefer! If there are more people who prefer the current style of the wiki, we might give the wiki style just a few small upgrades & tweaks, if the new style wins we'll upgrade to the new wiki style and customize it for our wiki. Here are both styles, in "TanamiLeft" (the current one) it's possible to change the color of the navigation menu and the top banner, in the "Moderna" theme we can only change the top banner background color, the navigation would stay grey. (But we might upgrade to a Premium Wiki to enable custom CSS styles.) TanamiLeft: Moderna: (ATTENTION: In this screen the color of the inactive links in the navigation menu is not fixed!)
Moderna is sleek and presentable, plus looks more professional from a design point of view. However, content looks the same on both and content is really the driving point of this Wiki. So I'm fine with either style. However, more customistation could be beneficial in the long run... You could open up a donation pool so that the community can help out with costs for a premium subscription too. I'd be more than willing to contribute.
The subscription costs 5$ per month. Currently from YouTube ads I get about 10euros (~7$) per month. I already earned about 70 euros (~65$) for the 6 last months in total, so the subscription would've been already paid with it inclusive the ProjectDIVA.NET url itself. A subscription would also increase our maximum file size for uploads from 10MB per file to 20MB (good for mp3s etc.) and a bit more webspace. Also with the custom CSS themes we could try to include some neat stuff into the wiki theme (maybe Suyo has some ideas for CSS coding?).
