Admin Forum:I need help with an user I'm having problem with.

Hello, Wikia support. I'm having problems with the user x10018ro on my wiki (Blueflake Wiki), and as an admin there, I'm tired to have him as a bureaucrat. I'm also a bureaucrat but I cannot remove his rights, I'm just so dissappointed and tired to have him as a bureaucrat. Everything starts here: Blueflake is a coming soon game company we're planning to have as an actual website in either 2012 - 2013. Well... We're having this wiki as the website for now, but still it's a wiki for articles. This user, x10018ro (aka Robin) says he's the founder (wich I used to believe it was true) but he's not. Ok.Blueflake started up when x10018ro uploaded a scanned drawing of his own in Nitrome Wiki, then people came and pixeled the image he made (a game). While all this was happening, I was making games, and actually planned to have my own website called JuanJLF (my real name). One day they decided to create this wiki, with the name Blueflake as the name of the company of THEIR game. The game was called Panbus. Sometime later they created Klotthead, another game (BEFORE CONTINUEING: ALL THIS GAMES are only pixel art, we're searching for programmers) they made. I decided to join Blueflake as a staff because I thought myself it was going to be quite hard to create a website and a wiki by my own and I needed help. This is when I really knew x10018ro. He only created the name of the company, and a hand drawing of Panbus before it could be a game but I still couldn't believe that was the roll of a founder. He didn't have any job here, the jobs are: Pixel artist (wich is mine), Programmer, Music Composer, Tester & Level Builder. He didn't have any of these. Now about the wiki, he doesn't even edit much here, as me and Axiy (another pixel artist) do and we both are planning to take controll of all this, since we are the only ones who made everything here. x10018ro wasn't even the founder of this wiki, but he forced Axiy (the real founder) to make him an admin and a bureaucrat. Making it shorter, it's just to make him leave this company/wiki. We will change its name and we'll delete all (few) things he made. I AM VERY TIRED AND I'M ASKING FOR YOUR HELP. Thank you for your attention. -- The Nitrome Yeti
