What is your username? 
Please link to the wiki here: http://the-solar-system.wikia.com/wiki/The_Solar_System_Wiki
I have 23 edits on this wiki, and have been the only contributor, besides an anonymous user, who has contributed in the past few months.
How many days/months have you been editing there?
I have been editing here since April 15th of 2013.
On the Special Pages → Special:ListUsers when was the last time an admin edited, and who was it?
I am unsure, but I'm guessing it was the wiki's founder, 123kitten1, a few months back before he was banned from all of wikia for being 12 years old.
Any other information: I've been editing this wiki since the founder was banned, and have been one of the few editors on the wiki.
