Hi and welcome Garbonzo,
My name is Teeny Pyjamas. I am an active JW, although I am an atheists and am only still in until they finally figure out who I am and disfellowship me. I am the founder of the www.AtheistsWeekly.com website. I created it for people who have always thought there was something seriously wrong with the Bible.
As we are currently working on improving the site, I advise you visit AtheistsWeekly.blogspot.com for the time being. I am also the founding member of www.JehovahsWitnessBlog.com. You can go there for all your other JW non-truths and needs. Use JWB as a supplementary guide. You can find out all you ever need, right here, on JWN.
With regards to your idea of a site, it simply wouldn't work, as I think we "apostates" would possibly take over.
Can I ask why you think evolution is ridiculous? Read through some of the articles on Atheists Weekly or some of the posts on here. I think you'll find it's the Bible's account of creation that is completely and utterly ridiculous.
My two cents...
