We just launched our affiliate program for our niche sites, including our 2 pregnant sites. We update the sites a few times a week and care both about our members, and the niche itself. Our affiliate program is run by a trusted 3rd party as well (PSW Billing), so no danger of shaving -- hits OR signups.
E-mail me directly if you want a login and password to look at the sites so you know what we offer surfers.
