If you are really unsure of what happened to a post you can send a pm to the moderator of that forum asking if they know what happened. It is of course best to ask in a "nice" way. They may say that it didn't meet permies guidelines, like it seemed like a "cider press" forum kind of topic, or maybe it got lost in a slow connection.
Paul has enough on his plate, I advise not asking him questions that someone else might be able to answer.
There's a lot of junk that gets posted on forums, including piles of spam, so moderators don't make it a habit to inform everyone they delete but nice people who ask politely and take
the answer they get with grace will get along fine. One of the best things about permies is that members are not allowed to get into the nasty insult matches that one finds all over the internet, so we mostly focus on
permaculture.
