I started a network and community site for motorcycle enthusiasts. Bikers Realm Working on a calendar application to list rides across the country and will be adding soon. Thanks for looking.
An issue here are the flash animation´s sizes, it makes your site really slow. Maybe you should decrease their sizes to make it ligther. If you want to start a serious community, i would take out the Google ads below the menu, it´s there to only catch some mistake clicks. It could make your members mad. The ads below the login are confusing too. Place your login in the header, besides your Logo. Don´t try to confuse people, they won´t click in your ads. The importance here is the content. If your content is good, they will click the ads. keep trying and try to make your site faster. Good job and good luck.
grevan has given you good advice. The site is slow to load and I'm no fan of white text on a dark background - but I'm not your target market so that may not be an issue. From the home page I found it hard to work out what your site is about. Is it social bookmarking? news? forum? It doesn't need to have a huge amount of text but some explanation would be good. there are a whole lot of empty "headline here" boxes - you should start generating some content before asking for reviews - that or just remove them. I tried to click on one of the news items but it went nowhere. It would be useful to have a static version that wasn't about to scroll away from me.
