I love the Ladies Lounge, and I honestly can't see any way to improve it.
While I'm not a parent myself, I agree that a special area for parents would be a nice addition. However, many of the issues brought up there could likely fit into Tilted Living, so I don't see it as a necessity.
Since I've joined TFP, I've never felt uncomfortable or out of place for being a female, so I don't feel the need to 'improve' anything.
Sorry Nikki, that wasn't entirely helpful.
And btw, I love your new avatar!
