I believe we left off at "I," the last entry that I was aware of being the Howling Dragon. Of course, it's possible that someone posted an "I" entry that I didn't get a chance to see before the boards crashed, so there's that possibility.
But in any case, I'm fine with letting this die. It had a 9-month run and it only stopped due to circumstances beyond our control. Of course, I'm also fine with picking up where we left off, although we'll probably never recover all of the pictures of the monsters listed above.
In any case, kudos to all participants in this thread. It's been fun!
