Hi there!
I will be joining this challenge, too. My goal is to reach 92 kilos by October (so, a lose of about 5 kilos). Would like to hope for more, but winter is here and is getting very hard to diet properly.
My weigh in is on Mondays/Tuesdays, so tomorrow I will be posting my initial weight (last time I weighed I was 97.1, but I can't remember the day).
