Wizards of the Coast in Jan. 2001 sponsored a prestige class contest on the company's messageboards, and, I assume, announced the results mid-April. Unlike the earlier spellwriting contest that saw winners' spells published on the Wizards main site, winning prestige classes seem confined to the now-gone Dungeons & Dragons Boards.
Some contest entries are archived here, but the first message in the subboard that I suspect contains the names of the winning prestige classes—much to my frustration—is not archived.
According to an ENWorld thread the prestige class the longblades won the contest, yet the entry was posted mid-March, about two weeks after the (supposed?) end-of-Feb. deadline. Further, the Internet Archive doesn't have an index for messages from that far back, having nothing before late March.
What prestige classes won the Jan. 2001 Wizard of the Coast-sponsored prestige class creation contest? Are these winning classes available elsewhere?
