First let me apologize for writing to the list without changing the subject of an earlier reply to a posting in the digest. I have noticed recently that questions about ZClasses tend to go unanswered. People who enquire about the documentation of ZClasses are pointed to the out-of-date ZClass tutorial on the old server. Amos had previously announced that he had submitted an updated ZClass tutorial for approval, but the recent announcement of updated documentation did not include a reference to the ZClass tutorial. I have not noticed any recent postings by Amos, so I would like to ask DC publically about the status of the new ZClass tutorial.
