Dan Wallace was my Greek professor at Dallas Seminary, and he did our pre-marrital counseling. He was my favorite seminary professor, and I spent many hours at his home in the summers practicing Greek, drinking rediculously strong coffee and watching Monty Python. I owe a great debt to Dr. Wallace, which I doubt he knows.
Dan Wallace is the general editor of the NET Bible (my favorite version, by far, though I use many).
This is the main web source for his resources, which are mostly short papers on intereting Biblical topics.
His History of the English Bible articles and audio lectures are simply amazing!
Not everyone likes him, for example, note this webpage devoted to calling him a heretic.
