     <p>So should you run a normal relay or bridge relay? If you have

 lots

     to <a href="#ExitPolicies">be an exit</a>, you should definitely

     run a normal relay, since we need more exits. If you can't be an
1660 1662
     exit and only have a little bit of bandwidth, be a bridge. Thanks
