Sometimes my posts won't post at all. Then I get this message, "you need to write something to make a reply." When it's whirling like that, trying to make the reply post, I have learned to copy my text, then wait and paste it into a new reply window. I live in a remote, rural area and I usually chalk it up to my "wireless broadband" service. But just in case it isn't, I thought I'd chime in here.

Above is what I am talking about. At first it showed no reply from me, so I re-did the reply. Now I see it turned out to be a double post, so I edited out the duplicate.
