I've got another one too that I just thought of :P
When you are in Live play, automatically disable the site's opening explorer from being viewed by that user until they close the Live window. I played recently against a guy who I swear was using it. Yeah, people could still go to another site or use a different reference, but at least they wouldn't get the idea to use this one.
Here's an idea, make some sort of community commentary system on the tactics training for those who aren't actually understanding the results. I've come across a few that I have no idea why the solution was what it was.
You could have some kind of voting or scoring system so the highest voted commentary or comment thing is shown.
