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) wikia!
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.
