Nefario taught an english class in china. he had some assignment where he got his students to do something on the forum. That's all I can remember.
It looks like most of the posts are from 2011. It is interesting to see that the forum has gone from being small enough to make a subform for a class or two of students to having millions of posts made every month.
Both the forum and bitcoin has come a long way in only 4 short years
