If you’re looking for something as your “+20” for COIL’s “100+20” recommendation for monetization of web page(s), here’s an idea: a read-thru (by you, the web creator) of your page, with the text highlighted as you read. It really personalizes the page when users hear your voice reading your own words. This is what I’m using on my site, for my 400+ math lessons. The linked page (below) gives complete instructions (HTML/CSS/JavaScript), plus an example of how it works.

You’ll want to visit the lesson page both as a COILed subscriber, and not, to see the different behavior in these two situations. (Be sure to click the green audio button at the top.)
Feel free to contact me (Carol JVF Burns; email on my homepage) if you’re interested in instructions on how I implement the timed delay and drop-down info box.
