Thank you for sharing this practical and easy-to-follow guide Bluedrem. Although we've talked before about this notifiers several times in the forum (I see that you've added some links in the bottom of your OP, thank you for that) the fact is that I think that it never hurts to remember that these tools exist, especially in Beginners & Help, so that newbies can use it too.
I've been using it for years and I rely on it in such a way that has become essential for tracking the forum, so I don't know what I would do if it stopped working one day.
