Wards Wiki is the first in a huge family of wiki variations. As the prototypical wiki, it is missing a lot of features supported by Hyper Text Markup Language and other more modern wikis such as Media Wiki. Most of the omissions are intentional Wiki Design Principles.

Custom fonts
Text color and background color
Other markup, like strikeout and underline
