If you've got a simple column layout, it's failry easily to collapse it into one column for mobile phones. If the page is full of tables of images or links, it'll be harder but with some CSS it is possible. If you're using a slideshow then that is much harder but then it's Wikia's job to maintian those, not ours.

That's with CSS support. Without it, I have no idea what you would do. I run an independant wiki :)
