Twitter questions/help? Please? :)?

So, A long time ago I changed my account so people had to request to follow me on twitter...how do i undo that? Like, I want people to just be able to click "follow" and be able to follow me. Cause whenever I go on, in the corner it will say "2 new follower requests" so...i did something that made it so they had to request to follow me and i just want them to be able to click it and see my stuff and follow me. Just like how celebs and stuff have it. Any way to do that? Thanks!
