and my answer is YES as i have won Member of the day contest continuously three days and one time two days...... and that time i have seen their is no much activity from other members so i think that why i got that prize and as per my knowledge Jambhasa have won this contest more than 50 times and he have record to win this contest daily it is 2 months ago i think.....
and if you keep activity and do good posting sure admin will chose you as member of the day....
Well, I think the answer is "no" because yesterday I really made many posts in other sections with the desire to win the prize two days continuous but still I was not selected as a winner. I think the admin wanted to share prizes with all members so he always chooses different members every day. Anyway, I appreciate it and from now onwards I will try only once or twice in a week, as even if we try daily it will be of no use.
