Changed page structure to topics -> Posts -> PostEntry. I no longer have a homepage but i'll be adding it back in. Added NumberOfPosts and LatestPost to Category.
Also added user session check into every page. if there's no user in the session, the webpage will redirect to the login page. Also changed link from homepage to posts.aspx on main page. laid out pages.css a little better with headers saying where the styles are used. still need to finish that!
