Right, this is going to sound very, very egotistical, but it’s just something that needs doing.
Sp, as of Thursday 25 October 2012, I am saying, right here. No, you cannot use my likeness, any part of my life or such in your comics or such without my express permission. If any comics, prints, essays, digital versions, future media and suchlike exist featuring me, I would prefer that all future editions remove all reference to me entirely and any monies made from work featuring myself be donated to either Shelter or Mind.
