What is your username? Hathomirr
Please link to the wiki here: http://tsutomu-nihei.wikia.com/wiki/Tsutomu_Nihei_Wiki
How many edits have you made on that wiki? 362 (at the time of making this request)
How many days/months have you been editing there? My current span of edits has lasted for roughly a week, though I had been making regular edits a year earlier.
On the Special Pages → Special:ListAdmins when was the last time an admin edited, and who was it? "Chengxia" is the only admin of the wiki and has not made an edit since August 1, 2013.
Any other information: I was initially planning on creating this wiki myself before I saw that it already existed, albeit with only a couple articles and images on it before being abandoned. I had planned on adopting it a year ago, but I had already adopted another wiki around that time and did not get around to it again until now.
I've made two attempts at contacting the admin on their message wall (once a year ago, and again this past week) - http://tsutomu-nihei.wikia.com/wiki/Message_Wall:Chengxia
There has been no other actual activity on the wiki since I originally arrived, and the admin does not appear to be active anywhere else.
