I have some of the more recent J/30 Journals which were newsletter style, including a stack of Vol 20, #1 mailed earlier this Summer to class members. I'd be happy to send you or anyone else a copy if you did not get one. Many were returned undeliverable by the US Postal Service. If you are a class member and did not get one, I may have an incorrect address for you.
In return for sending a J/30 Journal (current or back issue) I'd expect you to at least consider joining the class.
