I'm quite intrigued with this message system… So how does this work exactly? Do people know who send them a message? And how does it collect your information so send you confirmation that the message was sent?

Thank you for your feedback. People will know who sent the message. You will receive 3 confirm before sending the message.. at the moment there is not a read confirmation.. It could be the next feature :)

How do I know that in next 10 years this project will still be online.

If I die someone will receive the instructions (by messagerimus) to keep the project live :'D
