So, I've been thinking about building a performer of interest "watch list" to alert me when specific performers will be at the castle.
As a business and technology professional, I routinely design systems to solve problems for my clients; however, I no longer do much coding myself; I must rely upon others for the coding of the systems I design.

So what remains is to determine how to solve this problem. Let's break this down a bit.
The first step is to define the scope of the problem: The solution must take as input a page URL and a list of keywords (performers) and then check that page on schedule (e.g. 1x every 3 days). If a keyword match is found, send me a notification.
The closest solutions I have found so far are for web site monitoring and the one that appears to be most feature rich is Website Watcher. I'm certain this would work, but I prefer not to leave a task running on my PC.
I also noticed mention of some free and fee based on-line services that will apparently do the same. I know there are also some browser plugins that may be adapted. Ideally, I want a set it and forget it solution.
As a technologist, my mind is spinning with more ideas than necessary about ways to solve this, including many beyond my coding skills. The most elegant I could come up with would be a Raspberry PI inside a custom 3D printed case. This would run some kind of app to monitor the AMA web site for keyword matches and when found, send an alert, flash the LED beneath a glowing AMA logo or owl and perhaps play a magical audio chime to alert me of my favorite performer. Then, to acknowledge the alert, I could waive my hand over the AMA logo. (Overkill is wonderful, isn't it?)
For now, I'm content to find, build or collaborate with someone to come up with a simple solution.
