The BitcoinTalk SuperNotifier V2 has been a lifesaver for me.
I easily see topics that are new and comments that mention me on specific boards of interest. It has helped me to stay updated with what is going on in the forum.
It is not just about even making comments but reading the latest. And one of the most specific examples is when topics on phishing links, new scam methods, and all that stuff that can help me keep my bitcoin asset safe.
And the most fun you'll have with it is on April Fool's Day, when the admin decides to play some friendly tricks on us.
