This person is known to have contributed something to these pages, but I don't have an email address. This can happen for several reasons: I had an address but it was incorrect, I had it but it is no longer valid, I never had it at all, etc. Indeed, the person may not even be on the Net; for completeness and possible future use, I've placed links on the names of several frequently-mentioned, well-known jugglers in these pages.
If you really want to try to get in touch with this person, I suggest searching the rec.juggling archives -- if that doesn't work, you could try posting to rec.juggling. If you learn anything, please let me know so I can update the credits list.
