You were Officially warned for inactivity and then demoted. Like onion said it would be better for you to go for moderator since this will prove to us you are able to stick around. If you are truly going to stick around it wouldn't be a difficulty for you to go for moderator and then apply for admin when the time is right. If you do choose to go for moderator change your title to lock and your post to "I dont want this application to be voted upon in the meeting".

Good luck!
