Muthead handles their own support on muthead.com. If you find an error, need a nickname change or need help with one of the tools on the website then you will need to contact a moderator.
Contacting A Moderator
Contacting a moderator is fairly easy to do. You will need to go to the moderator page which can be found here: http://www.muthead.com/moderators. The moderator page looks like the image below.
Once on this page, you will see a list of moderators. You can choose to contact any of the moderators. However, the moderators with the green headers are the moderators that are currently online and active.
