I feel that the homepage summary/mission statement will turn JWs off from wanting to participate at all. JWFacts is an awesome, informative site designed to draw the Blue Pills into reading the truth about the Organization.
Cedars has his articles written from a balanced perspective so that readers can arrive at the conclusions themselves. He also has the annual jw survey that lets anyone associated with the Watchtower in any degree anonymously answer questions about their beliefs without being insulted or tricked. Its one of the most honest institutions you'll find online.
I'll let him link if he wants to.
I dunno if jwexam is yours or not, but that mission statement isn't beneficial to the cause and it doesn't edify the reader. If it's not your site but you are a supporter of its place in the fight for truth, I'd suggest petitioning the author to rewrite the homepage.
If it's yours, I petition you to rewrite it. If you need assistance, there are plenty who know how to word your desires so that you can draw Witnesses into the site. Cedars, James Woods, Terry, Blondie,and JWFacts just to name a few. I'm sure they would love to help train a soldier in this fight.
