You'd think there'd be a comm for it somewhere

Why are their no fandom mums or geek mums communities there's lj communities for just about everything else?
 
The comms that there are just don't really seem like my kind of place. It's not that the other comms weren't fangirl friendly, it was just that all the other pregnancy comms or friend-a-mum comms were either mostly medical questions or seemed to be filled with people who might not understand/approve of fandom and its fangirls or in a couple of cases even heard of them.

Based on the idea that I can't be the only expectant fangirl out there on lj I've created  fandom_mums 
I'm just rather stumped as to where to pimp the comm at. So far I've only posted at torch_wood_cafe being as it's sort of an off topic comm.

Any suggestions on where I could post a few adverts to?
