I stumbled upon this site when taking a trip down memory lane. Recalling the FILE_ID.DIZ file format[0] from my BBS days, I typed in the closest matching URL (file-id.biz) and found this curious interface.
I've only found one command so far after a bit of exploring:
help → "I am not what I am."

I did find that `ver` returns "FILE-ID.BIZ for the World Wide Web Version 1.2, (C) 2020" (default message).
And that commands are case-sensitive and white-space sensitive.
I'd be curious to see if anyone digs up anything else in the future. For now, I'm done with this little diversion.
