My friend Peter Nagy, a developer of the MRCC software, asked me how to get email notifications when people ask questions with the mrcc tag.
Surprisingly I could not remember how I did it years ago when I started following certain tags on other Stack Exchanges, and I couldn't find the answer easily on Meta Stack Exchange, for exmaple:
The accepted answer here: Email notifications for new questions matching specific tags, says you can't get emails, only RSS feeds, which is wrong/out-of-date. The acceptend answer here: Getting email notifications when comments or answers are posted, says you can get emails only for responses to your own questions and answers, which is also wrong/out-of-date.
So how is it done?
