Given that his HN name, "whunting", is a reference to "Good Will Hunting", that suggests OP might be a non-mathematician math enthusiast. I can't think of a single mathematician who would unironically name themselves after Good Will Hunting. I don't mean that in a disparaging way, though. Mathematics could really stand to stop taking itself so seriously and have people kidding around more, and that goes for myself as well! But it kind of flies in the face of OP's refusal to grant accounts to people without academic affiliation (MIT janitors like the film's protagonist probably don't have math department email addresses). The site being such high quality production despite being written entirely in PHP suggests OP is quite an unusual person, I'd really like to learn more about him.
