Use MessageMap to: • Anonymously post a message in a bottle and see where it ends up. • Find messages posted by others from all over the world. • Leave your mark - add a comment on bottles you find. • Watch bottles so you can come back to them later. • Track bottles you have posted and bottles you are watching, and see when others find and comment on them! Bottles and comments contain the approximate location of where they were posted, to give you an idea of where they came from, and so you can track the bottles you post as people from around the world find them and leave comments. Bottles sink after a few days, at which point they are no longer discoverable by other users.
