Becoming an affiliate is different to advertising, Manda.
You have to PM an Admin to request 'affiliateship' with your website name, url, description, age range rating (IE: PG, 18, or PG-13, M, etc.) and a 100x50 mini banner.
We will only accept sites that we think will be popular with the general member set. (IE: We won't accept affiliateship with a law firm, or a carpet shop, for example.)
