Edit a question (from other user) and get +2 rep ?
In the above question I upvoted the currently top voted answer. When I upvoted it it changed from 2 to 3. Now it has 6 votes.
My Recent Activity area (click the envelope on the top) shows that I have gained 5 reputation for an upvoted question and 2 reputation for one thing on the question above which is probably the upvote I gave since that is the only thing I did. It also shows the total of seven on the reputation tab.
How is this calculated that I get 2 reputation for an upvote? It never happened before.
