I'm going virtual tonight and I'd like you all to join me, or at least the virtual version of me -- Arianna Hera -- tonight at 9 p.m. ET. I couldn't pass up the invitation to join our friends at iVillage as they launch their first "Girls Night Out" in the virtual realm of Second Life, an online world with over 1.9 million residents. We'll be meeting at the sleek iVillage Loft on Sheep Island, where we'll be given a brief history of Second Life, and then head out to visit museums, design studios, and hear a musical performance. I'm also going to be looking for office space for our new virtual HuffPost offices. To join me, click here for directions. It should be a lot of fun. See you in the virtual world!
