Please don't get too upset about you being demoted. Sly said that there would be a chance that people would have a chance to be repremoted in the future, so it doesn't mean that you will never be an admin again.
It still is a chance, just without a title. Just keep giving helpful edits, helping others, making a few friends along the way, and you'll be just as recognised as an admin! :) Ask HowILoveIt; for the first few months, he was a super contributor and a reasonable friend, yet never asked for admin. He remains a respectable friend and good contributor now. And he's one of the people most well-regarded in the wiki. Be as sociable and active as him (maybe take out the sarcasm he has. You'd say that that is "aggressive" and "overreacting") and you'll be a great user and even considered by the staff for future adminship! ;)
