I once use notifier before which really helps me to track all the reply on my comment. One thing that I dont like about this notification is if someone that you didnt like reply or mention on a post that you didnt want to read. Theres no feature back then to exclude user by notifying which defeats the purpose of ignore button feature of the forum.
That's not true, though. There is an "ignored users" and "ignored topics" feature right in the bot's menu.
- Ignore members or topics so you don't get notifications from them.
To add, I am also using what LoyceV has made in the past for monitoring the topics or posts created by specific forum members[1]. And as far as I know, Tryninja is also planning to add a similar feature to his Bitcointalk Supernotifier bot, but I am not sure when it will be implemented.
It's already live. You can track/follow users (by new posts/topics) and even boards (new topics).
