I appreciate that the subject was discussed, opinions were shared and a solution was found.......... I appreciate that all the threads to be shared on facebook are started by "Mothering", and I think it shows the administrators here are part of, and concerned about, the community.
I looked at a couple threads started by Mothering and saw several mamas posting there who had pictures of their kids as avatars, usernames that could be real names, and didn't look at the siggys but it's probable that some had their kids b'days in the siggys.......
I still think mothering.com has the responsibility of informing every user that threads started by Mothering may be posted on facebook.
Whether it is with something in the signature ( I think this is preferable because it would keep new members informed) or a pm sent to all members of this community, I feel that it is important to do so immediately! As a lot of mamas have pictures of their kids, birthdays, real names displayed everytime they post and a lot of them would probably want to change that if they knew it was being posted to facebook.
I believe mothering.com has the right to re-post threads elsewhere, but PLEASE inform EVERY SINGLE MEMBER about this and how to identify which threads!! It is not enough that only the members who read this thread know about it!!
