You'd have to send an email to one of the forum's administrators. You should be able to find drh's email online. Incidentally, the parent message is marked "Deleted" because that's how Fossil "deletes" a forum post: it adds an edit to the post's block chain with a blank body. The OP clearly posted their question in the subject without a body, thus giving this presentation. I'd class this as a minor bug in the forum, since the parent post is the root of its forum thread; the "Deleted" presentation should apply only if the presented post has a parent artifact. Perhaps someone will fix it.
