There are categories for trying to conceive, parenting, pregnancy, etc. Why isn’t there any category for ADOPTION?

I have a new parenting and pregnancy forum that has been live since the 10th April (http://www.precious-babes.com) it is sponsored by another forum that is generating some traffic but I am not getting enough members actually registering, I have done lots of free submits google, yahoo – links on Myspace etc.
Where would you recommend the best place to advertise to get members registering and active? Thanks in advance

I am trying to find a good/homey parenting/womens forum. Someplace not too big, but not so small that there are few new topics.
Please send me your links!!

As the title says but i have a fab little forum which is all live but could do with some extra members – you type in pregnant to parent and it comes up but i if i were someone who wanted too find a pregnancy, ttc, parenting forum – how do i get it too pop up in those search results. Any replies greatly appreciated thank you!
