So not more than 10 minutes ago I had 964 rep:
I then signed up for programmers.stackexchange. Within this process I may have linked another openid to my account (is there a way to see all associated openids?)
Then I returned to stackoverflow to find I had gained 100 rep:
Nothing has changed on my history, and it wasn't from having another account go over 200 because none of my accounts have gone over 200 in nearly a year.
My activity feed doesn't shed any light on the situation, so my question is:
Where did the rep come from?
Not that I'm complaining or anything....
