when you say enhancements, i wonder this...
did the boards look like this when you posted? are you thinking about the old bbs? you can try the url http://oldbbs.burningman.com/
otherwise if the thread became inactive, the system may be set to auto delete after a certain amount of time.
hope that helps...
