Stats, stats and more stats

About the site, about the user... a graph to see how many users (of the site and of the house) were online and when in the week/day. A graph to see when you're the more active, and stats about you and yourself : how many HW you submitted, how many messages you post in the chat, the average number of points you earn in a week, etc ! Maybe these last "personal" infos not accessible to everyone ?
