I checked a thread http://www.acollegehand.com/viewtopic.php?f=18&t=18 If you can keep providing real useful information for your visitors,people will much willing to register. Besides,you need more threads/posts,more useful information for your visitors. Good luck
it looks pretty good to me (i've been using a pretty similar looking one about law school). i think the only way you're going to get more traffic is word of mouth (although I'm not at all an expert). But it's definitely user friendly!
