Please link to the wiki here: Horry Henry Wiki
How many edits have you made on that wiki? 81
How many days/months have you been editing there? I have been editing since April 16, 2015, though I've only been active now and again.
On the Special Pages → Special:ListAdmins when was the last time an admin edited, and who was it? It was BallisticBiscuit (who is globally blocked). He edited on July 26, 2014.
Any other information: The wiki has mostly been inactive.
- Unofficial response: (Please wait for an official response by a staff member)If you only edit from time to time,you probably won't be able to adopt it. Also since you said the wiki was mostly inactive,if there are other users from time to time,you should create a blog post about new admins. --Excuse me for breaking that wall 13:28, December 23, 2015 (UTC)
