With regards to the logo, I would personally go with a padlock. Design it implementing some perspective so it's zooming out the base of the logo. Sure the umbrella is easier but you'll gain more satisfaction from adding/designing the padlock and not to mention the padlock just seems more fitting to your sites niche.

I'll leave other members of the community to make suggestions on your frontpage.

Getting people to register and post. Well, firstly.. give them the kind of content that will entice those guests to register and want to post. You have a nice design, now you need the content to entice them. It's easy to get guests to register, it's a hell of a lot harder to get them to post. I'm sure plenty of the big board admins can give better advice on this subject and I'm just them will give you plenty of tips/suggestions shortly.
