Hi. I’ve given you admin and bureaucrat rights on this community as you requested. You now have the tools you need to clean up, customize and maintain the wiki.
Check out Wiki Features to see which features you can enable (or disable) on your wiki, including chat, forum, and many more. If you have adopted an older community with talk pages you can also enable message walls and article comments here.
Customize your community’'s look by visiting the Theme Designer, where you can add color and style to your background and wordmark for your desktop visitors.
Look through the various useful reports available at Special:Insights including popular pages, uncategorized pages, and wanted pages for ideas on ways to improve your community.
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!
