I just posted a message to the Las Vegas thread, and it didn't post. Luckily, I have gotten into the habit of saving most messages before posting. All it takes is to hit [CTRL-A] (highlight all) and [CTRL-C] (copy all), and you've saved it. Then go back to your message to see if it posted. If it didn't, hit [CTRL-V] (paste), and submit the message again. You may want to refresh [F5] the thread to give your message a better chance of posting.
