I wish you good luck with this application. You'd seem like a great addition to the staff team and I think you're very mature and have a wide knowledge of the rules. You could handle the Enforcer role again.
The Senior Administration team do not feel you are ready for this position, reasons for this include your lack of activity and determination during your period as Enforcer previously. Your conduct upon leaving the community shortly afterwards was also unacceptable and does not bode well for a potential candidate.
