To log on and post you will need to create an account in the forums even if you already registered on the main Hotness Rater site. These registrations are separate.
I think you're missing out on a key tool to move some traffic from Hotnessrater to Babesrater. A "See _____ Nude" button next to Hotnessrater pics that apply would be quite popular.
Currently in the external links we should have links to the girls babesrater site. I am a little reluctant to specifically put the word nude on HotnessRater just because as far as advertisers are concerned, we technically shouldn't have any nude pictures or links to nudes.
