On the Special Pages → Special:ListUsers when was the last time an admin edited, and who was it?
Any other information:

Unofficial response: (Please wait for an official response by a staff member)
Hello. Joseph is correct; you must use Special:Contact in order to request that a wikia be closed (or merged). Adoption requests are to gain rights on a wikia with no other active admins. -- Wendy (talk) 04:15, January 5, 2015 (UTC)
