RSnyden: Just out of curiosity: Is it possible for someone to gain 3 points of reputation without posting anything?
I just saw a user gain reputation, when he hasn't posted anything for the last week.
I know you gain 1 point for posting something, and more points if you get high-rated, so I don't know how it is possible to gain points without posting.
By having posts up-voted. It doesn't matter when the up-voted post(s) was(were) posted but when the post(s) was(were) up-voted. It's then you will see a change in rep. Same with down-votes.
