Hello there!

I also made a script that gets the answers to teachometer,
To use that script, drag this link (Teachometer Answers) to your bookmarks bar and when you are on a teachometer page, click the bookmark.
The source code for the teachometer script and the client side of the dfm script are public on my github.
