Well I've taken it on myself to do as much as I can for this wiki. Today I began at looking at extracting images from the .pak files, images that could be used on the Wiki. I really was unsure if I could do this, and it's a long story, but I guess my programming experience helped in coding some C# on top of the code that created the .paks to extract the .xnbs. However, standard XNB to PNG converters such as the one for Terraria didn't work. I then found a paint.NET extension. I've never been so happy to see a pistol sprite in all its glory.
On the wiki I am still creating templates and infoboxes, building the framework so that lots of pages can be standardised when the time comes.
