The Wikia tour is a project under development that will tour you through active Wikia sites, along the lines of the Wiki Tour Bus. The Central Wikia was formerly added to the Wiki Tour Bus with the option of diverging from the main tour into the Wikia tour, but for technical reasons that linkage is not current.
Links to mini-tours of individual Wikia can be found on the list on Community Central, and the opening and closing pages of those tours are each a modified copy of the box below (which is not meant to work properly on Community Central, which does not have its own tour).
It is fairly easy to create your own mini-tour, since you copy a few pages from Community Central to your wiki, including a simple template that provides a header box and transcludes content from your selection of existing pages on your wiki. You don't need to create any new content, other than adding an introductory "commentary" to each tour subpage that includes a transcluded page.
Once your Wikia has its tour working, you may follow a few more simple steps to link it into the tour network. It is easy to insert other pages in it before or after it is linked.
Want to help us create a new Wikia tour? There is an archived forum about it, but the idea has been superseded by other Wikia improvements.
