I just noticed something called reputation points, but I can't find anything about what they mean anywhere (FAQs, TOU). What are reputation points and how do they work? How does one bestow a reputation point? Can they be taken away? And what is a good number? I see I have 33 points. Is that good? Or bad? Is that out of some total, like 100? Do I get a prize if I reach a certain number (like being able to read PMs after 50 posts)?
