Conversation plug-ins open in the conversation window and let you look at what you’re talking about with a friend – while you’re talking about it. Inviting a friend to look at photos together is a good example of how a conversation plug-in works.

Tab plug-ins, located below your friends list, don’t require a conversation. Think of them as some of your daily reference points, where you can monitor an auction or view your calendar, check Finance or News, or keep an eye on a score (or play a game of your own, with a friend). You can also order stuff, or watch a video. And lots more!
