The Facebook group would be great. I'll get on it after work.
If it's not secret, it can show up in peoples newsfeeds as groups suggestions. Are we ok with any June Mummy joining or would we prefer it to be just pregnancyforum Mums? We may get lots of people joining, if we keep it a closed group and the title as it is.
I joined a Facebook group that was created from a similar page to this (I am pregnant.com) and 6 years later we are still friends and some of us have even visited each other.
