Load a save and up in the left corner it will say something like: "Press F3 to go online". After you've done that, you enter a name and press Enter. Now you're online. The mod has a lot of bugs and glitches. Everyone appears to be nude, except yourself, and there are no animations on other players. Some players may seem to float in mid-air from time to time. There's a chat window and a friend list. Press F3 to interact with those windows. When you die, you just load a save and press F3 again. Vendors work fine, as well as the console. You can also go in and out of zones and fast travel."
