The hub backend was upgraded to vbulletin 4.1.6 that comes many bug fixes and new features. One of the new features is a full-fledged editor that has an auto save feature. If you accidentally refresh the page or your browser crashes, the auto save can retrieve the saved text for you. Unfortunately, the new editor does not work well with the custom features we implemented (tamil typing, etc.) earlier. So you'll see some strange behaviour or messages. Pls be patient. We are in the process of fixing them.
