I typed a reply and then got distracted a few minutes and then finished the reply and clicled the Post button and then I looked around at something else and then when I looked back I saw a message saying that at post cannot be blank and everything I had typed was gone. I am not sure what happened but there might be a problem with the forum software. To avoid possible loss of data, copy your post to the clipboard before posting then wait and ensure that it is successful. If the problem happens to you then post here.
