It is nonetheless very important to maintain transparency. I think whenever you delete a message, you should fess up to it and put in a placeholder in the thread. I don't want to call you a liar, but I think there are certainly situations where differing understandings of a sequence of events leads to people thinking you're being something less than truthful. When you delete or move messages, it results in a thread which doesn't match up with the thread as it is delivered to our email inbox (when we're subscribed through email). When I see discrepancies with the messages as delivered in realtime to my email account versus what is actually on the forum, I tend to feel a little upset and view things on this forum a bit more skeptically. If you state your actions in the thread upon which you are acting, that prevents members from thinking you're trying to be a revisionist historian with the flow of the discussion.
