Wiki Features
Wiki Features is a SpecialPage that allows admins and founders to enable or disable some of Wikia's optional features on their wiki. Optional features are listed with a description and a "Enable/Disable" switch. All users can see Wiki Features, but only admins can toggle the switch turning features on or off.
Wiki Features is found within the Admin Dashboard or directly by going to Special:WikiFeatures.
Wiki Features has two different areas: Features and Labs.
Features
Features are optional features for your wiki that are no longer being actively developed and are stable.
Currently Available: Polls, Top Ten Lists, Achievements, Layout Builder, Blogs, Article Comments, Category Exhibition.
Labs
Labs are new optional features that are currently within beta testing and are still within development. These features have not been launched site wide yet. You'll see how many wikis have each feature activated and will be able to send feedback about your experience with the feature.
