Grab your guitars, the NETA Nashville 2011 conference registration is now officially open. Once you've registered for the January event you can visit the confab's Facebook page. Not sure what that means? Then you'd better stop by the conference Social Media Help Desk while you're at the Loews Vanderbilt Hotel. That's a new kiosk that will be "staffed by friendly experts in the use of Facebook, Twitter, texting and all sorts of handheld devices, ready with advice or a helping hand."
