So I was up late last night trying to find out what it causing the message posting problems and discovered that there is a bug in the web server version that causes long posts to be truncated. To fix it I'm going to have to manually update the server to a newer version.
It may take a few days to fix (as I have a day job). For now you have to keep posts short. Sorry. You will get an error message if you try to post a long message.
