We'll try to notify the author when a post is deleted. But can't promise anything. It really depends on how much time and workload I and the moderators have at the moment.
Frankly, I don't see why there is so much worry about the deleted posts.
I'm a user of many other message boards on different topics. And my posts get deleted occasionally. Sometimes I get notices other times I don't. But I don't see it as a big deal.
I would get worried and start asking questions if every other post I make got deleted. But if it only happens once in a while, then I don't think of it as a problem.
Believe me, if we see something systematically wrong with someone's posts here, we'll contact that person and try to explain why we think it's wrong.
