When you post a Tripstr story to a Facebook album, the app creates a new Facebook album on your behalf. Your story's cover photo, title, tagline, and all photo captions are all included in the Facebook album. Your Tripstr story's Facebook album will not include any journal entries, photo "likes," or comments.
The resulting Facebook album is not synced with your Tripstr story. In other words, if you decide to make any changes to your Tripstr story, those changes will not be reflected in your Facebook album, nor will any changes you make to the album in Facebook be reflected in your Tripstr story. "Likes" and comments you receive via Facebook will not show up in your Tripstr story, either.
