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!
Since you're the most active here (and you're trying to adopt the wiki), I was wondering if I could add other Hot 100-related information to song articles, such as peak, position last seen at, weeks spent on chart, etc. After all, this is the Hot 100 wiki. :P
