- When you start a Wave with someone they can see everything that you're typing, images and videos that you're sharing and files that you add as you do it. It's live and there's no way to turn that setting off so make sure that you're not sharing anything over a Wave that you won't regret sharing later. Even if you delete something, the other person has most likely already seen it.

- When someone sends you something like a photo, you can instantly see it, comment on it, and even send your own right back.

- If you're collaborating on a project with people you can start a conversation with one person and invite others in later. They can click the "playback" button to see how the conversation was taking place so that nothing gets lost in translation.

- If you only want one person to see certain content in a Wave, click on the drop down menu next to an item in a wave and select "private conversation." Then select the person who you wish to share this with from your list of contacts.
