A while ago, I earned an association bonus. It was 100 reputation. Now every stackexchange site I sign up for under my email address automatically has 101 reputation. I was curious as to how these association bonuses work? How are they awarded?
you associate accounts of two or more Stack Exchange network sites, and at least one of those accounts already has 200 or more reputation: +100 on each site (awarded a maximum of one time per site).
