Pigeon Mail

Pigeon Mail is a free simple text messenger. It now seems to be bug-free and usable. Works fine on mobile browsers too. I guess text message apps aren't in high demand these days, but it may appeal to those who like simplicity and privacy (obviously Pigeon Mail isn't a part of a large social network) and don't like downloading stuff. This system is completely browser-based.
