Check out your Admin Dashboard, which can by found by clicking "Admin" on the bottom toolbar -- it has links to all your new tools. Please let me know if you have any questions, and good luck with your new (old) wiki!
I noticed that you seem to find a way as an alternative to the Switch template, and that's good ^^ When you have the admin rights when you've adopted the wiki, if you want, you can make the tabber look like the Switch by putting codes in the MediaWiki:Wikia.css which could result into this. Feel free to contact me anytime, I'd be willing to help.
Yeah, I'm currently hoping for admin rights cause as you can see the Wiki doesn't look too nice. I'm using the tabber right now, but it looks quite ugly in infoboxes so I was hoping to use them just for things like the footer on the main page.
Looking for live help? Then join us for an upcoming webinar to chat with staff and other Wikia editors. You can also check our Staff blog to keep up-to-date with the latest news and events around Wikia. Lastly, check out the Wikia Video Library, where you can find premium licensed videos to add to the wiki.
All of these links are a great way to start exploring Wikia.
