I've upgraded the forums to vBulletin 4.1.4, whose major new feature is that it has a WYSWIG editor for all WebKit based browsers (including auto-save). You can read more about the editor here: https://www.vbulletin.com/forum/entr...ed-by-CKEditor
You may need to do a hard refresh in the browser if you have trouble posting since the entire editor is different.
You can always switch back to source mode by clicking on the upper-left button if you need to fix any new problems caused by this editor.
As usual, please let me know if you run into bugs or other problems with the upgrade.
