Following from the new watched words feature that takes action on bad words, here’s a plugin that lets people save a list of searches and get notified if any new topics and posts are created that match their searches.
After installing the plugin, enable it and choose the minimum trust level to allow creating saved searches.
There’s a new section in your preferences where you can define your list of searches.
Once a day, your searches will be performed. If there are new results that you haven’t already seen, you’ll get a private message with a list of links to the posts. If you want to get an email notification, be sure you’ve enabled “Send me an email when someone messages me” in your email settings.
We’ve enabled it on meta for minimum trust level 2, so give it a try.
