I understand that you can see the thread on 23&me if you sign-up as a user (doesn't require taking the test, but giving them your email address). Frankly, I have a test there, but I find it the least useful of the big three DNA sites...too many tests for health (old ones) or ethnicity and I recently learned that many come into their system as part of some health test group (i.e. testing those who have or are concerned about a particular health condition) and those are mostly anonymous users who don't respond to queries. Some people have more time and patience to work thru their invite system and some of their tools are good. Most of the information on the ancestry.com dna thread on 23&me appears elsewhere, i.e. the ISOGG facebook or ISOGGDNA newbie listserv (not to be confused with the fairly worthless rootsweb dna newbie list serv), although the discussions on this 23&me thread are often informative about work that people are doing in using gedmatch, etc.
