Well, I'm married and have 5 kids. I've yet to be booted off!

I don't want to speak for other mods, but the specific forums aren't meant only for people whose lifestyle falls within the certain category covered by the site. I welcome all religions (or none) at LDS Families, and really value the opinions and experiences of others. I've posted in ethnic beauty even though my ethnicity is not what was intended when the stie and forum were born, and I've dropped in on Mexican Food even though I in no way resemble a burritto!

For me the point is that there is a lot of value in hearing about any subject from a variety of angles. This forum is clearly set up as one not intended to debate the wisdom or rightness of not having children, but to support and nurture those who do not. I would imagine a single-no-kidder would be just as welcome to seek support and nurturance. If I wanted suport, however, I'd probably be better to seek it in anotehr forum, but I hope my responding to someone who posts here would not be deemed intrusive or out of line.
If a married-no-kidder posts a topic here looking for insight, I may have a pov that can be of value even though I now am swimming in children. A person who is single no kids could offer a valuable insight from her perspective, and so on.
I understand the need for the automated note. When I was child-free there were no shortage of people-- strangers and acquaintences-- who felt very free to share their opinions of my life. (That we were struggling with infertility wasn't their
blank business, and when they discovered we were trying to have kids I had no use for their sudden sympathy and approval. I took to calling myself child-free out of defiance.) For some reason people feel quite justified in interrogating and advising others on the subject of how many children they do/do not/should/should not have.
