You should probably explain what it does. When I click your link, I get a message "how do you want to use messanger, web or app?". I clicked "web" and was greeted with a fb login page. At this point I gave up.

Errmm... It's a "facebook" messenger bot, I don't think you can use it without logging in.

But yup, I should provide a description here - so shall do it asap :)
