You can't create a new Collection until you have at least begun populating your Default Collection. Once you have searched for some Videos and added them, visit the Collections section and you will see a button to create another Collection.

By default, only your friends. If you would like to change this, just use the Edit Preferences screen for that Collection. You can use 'Public' to let anyone see it, or a more restrictive setting to increase privacy. If you make it to the leaderboard (Top 50) then anyone will be able to see the overall size of your Default Collection, but whether someone can see the contents of that Collection is subject to the normal rules.

Whether you can see another user's Collection is entirely up to that User. If you are their friend, you can see the Collection. If you aren't their friend, but they have set a Collection to be 'Public', then you and everyone else can see it. If you can't see a user's Collection and would like to, poke them or something and see if they'll let you have a peek.

Go to the Preferences section and use the Profile Options form to adjust your preferences--using the Preview button will provide you with the code needed to embed your Collection. You can also follow the <embed> links for each Collection from the Collections section, which will help you configure and preview your embed before providing you the code.

Think of it as a key that unlocks a specific one of your Collections. Until you provide one, we'll keep your Collection trapped and you will only be able to see it through the Flixville app in Facebook or through Flixville proper. But, if you provide one, we will let it be pulled elsewhere into the web, just as you can do with your Profile Collection.

Go to the Collections page and click the Pencil icon (Edit this Collection), then select the Preferences tab to edit that Collection's preferences and you will be able to enter the token there--10 characters, letters and numbers only. Other locations (<embed> links and Preferences) will sometimes prompt you to automatically generate one.

As of now, friend data is live, so there is no delay in data refreshing. There is a background process that refreshes several other items on the Home page every 20 minutes, and internal caching that lasts 5 minutes, so the longest it will ever sit without refreshing will be about 25 minutes. That's not to say something always changes in that 25 minutes, just to say that the data is never older than 25 minutes.

As of now, about once each hour. Like the Home page statistics, that's not to say something always changes in that hour, just to say that the data is never older than one hour.
