Adminship is granted, at present, without any method of easy removal of the user rights. A number of administrators have added themselves to Category:Wikipedia administrators open to recall. I am also happy to be open to recall. My requirements are uncomplicated;
If three or more of the following editors all make a formal good faith petition to me that I should no longer have admin rights then I will ask for them to be removed with immediate effect. The request must be signed by three editors within a seven day period. Editors who leave Wikipedia will be removed from the list. Others may be added.
