Subjunct lets you share secret messages. You choose what the recipient needs to know to access the message—a password? A piece of trivia? What they ate last night? Subjuncts are secrets guarded by other secrets.
Each message has a unique URL that you can use to share the message with friends. Some messages will also be featured on the home page—protected by their security queston, of course. Anyone can try to answer the question to see the message.
