I don't know if anyone has posted this anywhere or knows of a better calculator but I LOVE this one. It gives a breakdown of some macronutrients if you're interested as well as allowing for you to check off whether you are breastfeeding and/or pregnant.
I had found a different calculator a while back that actually accounted for whether you were breastfeeding <6 months or >6 months as the caloric needs will differ slightly because of the difference in milk production, but I haven't been able to find it since.

I believe the site you found was this one:
I used it while pregnant and breastfeeding.
That was the one!
I just see so many post starting with, "how many calories should I eat while [bf'ing/pregnant], and it's too bad that CC can't incorporate that into its calculations, but there are calculators out there that will account for that.
Thanks, Bier. ^.^
