This is very interesting to me. I started Russian and decided I should learn French before Russian so I didn't have to do as much with the alphabet. However I always get busy and stop for just long enough to forget most of what I learned. I will be eagerly watching for reviews of the process from people who have gone through it.

Site looks good, but I think some review of the readability of the bigger paragraphs could be done. Specifically the bullet points on the Guarantee page are a bit difficult to read. Also they are formatted different between Our Promise and Your Commitment, which you may have a good reason for.
