Admin Forum:How do I adopt/become admin for an abandoned wiki?

It appears that the "Cougar Town Wiki" has been abandoned. The site is underdeveloped, out of date and the admin username has been disabled. How do I adopt this wiki? I have edited and admin on several other wikis such as the Marvel Database and Seerowpedia. I've already begun to update the wiki, but I do not have access to the main page or deleting photos/pages. Thank you for your help.
