I too have thought of this. I try not to put too much info on here, but it can be hard when your giving advice. Such as age, name, location, and so forth. I try to keep it simple and not use my exact location or phone #. I think it is ok to give general info such as the city you live in, especially if you are looking for child care or some other venue. I have posted the location of my child's school and his name. I do know you have to "be invited" and fill out some info and you are approved by someone. I have no idea who does this and what criteria they have.
By the way, I love this site, as I don't know very many moms that can give good advice. I think the ones I do know get cought up in their own lives and don't pay attn. For example, I was always saying we had no sitter and we couldn't make it to anything because of it. No one could suggest anything, just "oh, that stinks for you". I ended up finding Adventure Kids in Flower Mound on my own. I found out, after trying to tell my freinds about it, that they already new about it and used it. This is not the first time something like this has happened. So, anyway, that is why I love this forum of real moms who give real advice and can get to the point (except me, because I tend to ramble on :).
Let us know what they find out.
Thanks,
