Check out your Admin Dashboard, which can be 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 the wiki!
I've recently started looking at this wiki, and I noticed you've been making a lot of edits here. So if you're interested, you might want to consider adopting the wiki. Doing so would give you administrator and bureaucrat rights, which means you'd have extra tools for cleaning up, managing pages, and other things. You can read more about adopting a wiki here.
EDIT: Actually, I see you're already familiar with the adoption process, but in any case, I believe you're eligible to adopt this wiki if you're interested.
