Yeah, I don't know that anyone here buys into the myth of the ancient Korean origins of TKD/TSD. Probably when the site was first built whoever created the subforums (Bob?) just copied and pasted the description from some random website.
I don't recall when we added the section, but most of the early art forum descriptions were based on available info in the rec.martialarts FAQ as it was at the time, or later distilled from Wikipedia entries. A few were updated, modified or totally replaced based on member input over the years.
