I'm curious why you need to post this topic. It has been done several times already, a quick search would have shown you this. I also wonder why you have not yet realised that this site no longer just deals with issues solely relating to parenthood? Are you perhaps a bit dim, or maybe a lazy DM journo, or both.
Just look at the broad spectrum of topics discussed on Mumsnet.
Some on Mumsnet are currently parents, some are long done with childrearing and enjoying their freedom, some decided having children wasn't for them, some sadly can't. All these people are multi-faceted human beings, capable of being interested in other subjects other those related solely to procreation and child rearing. I know (shock, horror), who knew.
I myself came via Penis Beaker and laughed so much (despite my child rearing days being well and truly over) that I stayed. I persuse the Pet section, S&B, AIBU, relationships, reading recommendations and follow a couple of Ops in their journey out of abusive relationships, willing them on to a better life. I also currently follow the house moving thread as have a vested interest in this subject at the moment.
There, I have very generously given my time in trying to educate you on something that should be evident, because I am a nice person; there are lots of nice, funny, intelligent people on here (not all Mums) and some batshit crazy and that is why we return to this site again and again. Oh, and like a p/p I like the swearing. I would be chucked off the other site due to my potty mouth. HTH.
