Is it still possible to use your mouse to hover over yellow words and phrases to see the hints instead of clicking on them?
Also, you mentioned somewhere that people who use the site regularly may be able to avoid having the use the Captcha. I find the numbers easy, but I have tried the letters for this post four times so far without success.
If you click on the two little arrows at the extreme right hand side , near the top of the lesson page, you can change to the minimized view and use the hover functionality. We are working on the speed issue and eliminating the captcha for regular forum users. Please be patient.
