What actions should I take if I have an idea for a website?

I must warn you all that I am very ignorant with this topic. All I have is basically an extremely well thought out idea for a website. I would like to share my idea with my peers to get feedback in order get a small grasp of how popular (accepted) my website would be. That’s the problem I don’t know if I should patent the idea before I start sharing it. I am just looking for some advice. Thanks.
