Inaccessibilty of CAPTCHA 2 W3C Editor's Draft 18 April 2018

1. There is a bad link at the very beginning of the W3C Editor's Draft 18 April 2018 of "Inaccessibilty of CAPTCHA 2 ":
"Latest published version:
"https://www.w3.org/TR/turingtest-2/"
That URL goes to a page at that address that says "DOCUMENT NOT FOUND".
2. The contact information for comments has doubled "@w3.org", i.e. public-aoa@w3.org@w3.org<mailto:public-aoa@w3.org@w3.org> instead of "@w3.org".  This affects the displayed email address as well as the subscribe and archives links.
             "Please send them to public-apa@w3.org@w3.org<mailto:public-apa@w3.org@w3.org> (subscribe<mailto:public-apa@w3.org-request@w3.org?subject=subscribe>,archives<https://lists.w3.org/Archives/Public/public-apa@w3.org/>)."
3. Thank you for this.  I was just doing research on CAPTCHAs, accessibility, and security.  This is immensely helpful.

P.S.: I didn't check other links.  These just happened to be ones I tried to use.
