Just one question: Is their karma supposed to be increased every time the log in and it's a new day, or every time they are logged in and it's a new day? I ask because I almost never have to log in to the arc forum; my session apparently lasts a long time, possibly lasting until I log in from a different computer or longer. As such, I never actually go through the official log in process, but I'm still online.
Does ensure-news-user get run on page load as part of the code that checks whether their logged in or not? From a cursory look at the code, it didn't appear to work that way.
How would you write it differently if you wanted to increase their karma for every day they logged on, as opposed to for day they logged in?
