I think that might solve the privacy issues.
I would like to be able, on my customise, make my name unsearchable under posts "posted by X".
Is that feasible?
I know it seems recently that the so-called "active" posters are unnecessary on here - in fact on another thread I have just noticed that we are apparently a minority 
and therefore have no right to dictate how the site is run.
However, in my opinion (and correct me if I'm wrong) the site would be very much less helpful to parents if the regulars stopped offering advice. There are many active posters on here who post in niche places, giving advice on things as far apart as legal, infertility, mental health, parenting, etc etc. For me, certainly, I'm no longer as happy to post about my life, and thus support others, when it is so easy with one click to post the whole thread straight to Facebook. Where I might be recognised because of my unusual circumstances, and someone can come straight here and read about my life, and my children's life, for the last ten years.
So I'm left with options: I can dereg and not post at all, I can post only on innane threads or I can lurk only.
In all of those choices I won't be giving advice and sympathy because I'm going to be bloody careful what I post.
Or you could make my user-name unsearchable.
