For example, how many topics are posted that are not directly related to having kids, or being a parent?
I am just writing up my dissertation (for which I interviewed members of Mumsnet) and I would just like to put in what sort of place MN is. I know that there are lots of threads that are nothing to do with children or parenting, I would just like something official I could write about IYSWIM.
I did see it discussed on a thread not too long ago but I can't find it now 
. Something along the lines of 'do you have to be a mum to post on here' .
