Dear WCAG WG,

EOWG accepts your resolutions below.

("WCAG 2.0 is great as is... Lets deliver it.: I have my opinions about things in WCAG 2.0 that could be better, but at this point I think they are hair splitting. In some areas I disagree with the responses, but not enough to argue it. And, I might be wrong. So, I think it is time to wrap 2.0 in a bow and send it to the universe."[1] "I agree. Let's move forward!"[2])

We are excited that you are progressing WCAG 2.0 closer to becoming a W3C Recommendation, Web standard. Congratulations.

Regards,
~Shawn Henry for EOWG[3]
