You can't, you can only unprotect them on the web version.
To unprotect your tweets go to settings and uncheck the protect tweets box.
No, that's why stalkers are thankful to twitter for they can view a person's tweets/profile freely unless their tweets are protected.
By going to your settings and un-ticking the box called "Protect my tweets".
You can't do this. You either protect your tweets and approve people to follow you or you unprotect your account and your tweets are viewable and anyone can follow you.
If your tweets are protected then only people following you can see your tweets. If she isn't following you then maybe she has access to an account that is following you.
No Mel Gibson is not on facebook but he is on Twitter but he has protected his tweets.
Yes he does. His username is 'DylanSprouse1' but he has protected his tweets so you need to send a request to see his tweets.
Any Twitter user can send you a tweet if your account/tweets aren't protected.
If you have protected tweets, you will see a follower request on the right hand side sidebar of your homepage. Click on it and you can decide if you want to accept or deny the request. If you don't have protected tweets, anyone can follow you without your permission.
i don't think you can reset your tweets on twitter.
If you included their full username (@username) then that tweet will appear in their @replies even if your account is protected.
