If you have art you made for the wiki which you want to show us, you could post it in bring & brag, or in the Choose Your Own Misadventure thread, or both, or neither.
Learning wikification is really really easy. You can probably figure it out just by clicking on any of the edit pages and looking at the code. To create an image on the wiki, first you have to upload it. Click on "upload file" in the toolbox on the left.
Then, you post the image with the code
you align it like this:
you fix the width like this:
you make it a thumbnail like this:
[image: filename.jpg|thumb|This is the caption text]
We try to keep the pics to under 300k or so, but don't be restrained by that if it's a really cool image.
Be bold and go have fun. Because each page only has a small chance of being hit, I'd really not sweat these images too hard. Don't spend too long crafting masterpieces that will be buried within the exponentially branching story. But DO be bold and have fun with it. We'd love to have a dedicated image-person who just improves the wiki by adding hilarious visual content. You really have an opportunity to deifine a lot of the visual jokes and style.
The wiki's felt a big stagnant recently, so I really encourage people to step up and make some new pages. Don't think of it as a task that we have to "finish this thing we started" or whatever. Do it because it really is quite fun once you get in the swing of it. After you've made a page or two, you'll be awesome at it. I had a LOT of fun making a lot of the pages there, and I think it shows.
Just be really ridiculous and think outside the spox.
