The idea here is sound: think of it like social marketing. You want to invite your friend in to Second Life but you get this little cringe when you think about them wading through sign-up, landing at orientation island, while you manically text them in Skype or MSN or whatever asking if they’ve logged in yet and what their user name is so you can send them a teleport, assuring them to just CLICK it, it’s safer over where you are or whatever and the prims are probably nicer.
