With the most recent forum software upgrade, we get a new, more powerful WSIWYG editor. The three main benefits to this new editor are:
1 - Auto save. As you are typing along, you should notice an autosave message in the lower right corner of the editor pop up from time to time telling you your message has been autosaved. If you leave the editor and then come back, you will have the option to restore your autosaved message
2 - Tables. You can now insert and manage tables in your posts
3 - Import Word type documents.
