As I understood before, the commitment can be fulfilled earliest with the second day of public beta, but the site is still in private beta (a bit longer than normal, for not enough questions). It would be the second day of public beta now if it would have gone with the original plan, though.
Is this simply an error, e.g. this script calculating the commitments was not informed about the longer private beta period? Or is there something wrong in the FAQ?
I committed to post at least 3 questions and answer any that I can during the beta period, if I remember right - I have two questions now (9 answers). From the proposal page, it seems that 3 people have fulfilled their commitment. Thomas Pornin has only one question (but 27 answers, most quite good, which may balance out), while Tangurena had no questions at all (11 answers).

p.s. Now that you've followed through on your commitment, you can commit to an additional site proposal! Check out the list at http://area51.stackexchange.com.
Also, if this mail is really meant to be sent while still in private beta, the Please share a link seems not really appropriate.
