First, when posting you will notice a new editor interface turned on by default. This new editor works much like a normal word processor (e.g. Microsoft Word) and hopefully makes formatting your posts easier. For those who prefer to edit the BBCode markup directly you can toggle between modes using the lightswitch button in the upper left corner of the toolbar.
Next, we've disabled further uploads to ImageGullet: any images that are there already will continue to be hosted, but in the future we ask that images be put into posts either as attachments, or linked to from another image host.
Finally, the new version of the software supports more extensive social networking options: you will notice a number of places around the forums where you can opt to share content with Facebook or Twitter, and if you choose to link your accounts you can easily update your status by clicking on your username at the top of the screen.
Of course there are myriad additional changes: click around and explore!
While the software provider and the Society for Culinary Arts & Letters have tested the software extensively, there will of course be some bugs in the new version: if you run across anything that doesn't seem to be working correctly, please send me a message. Thanks!
