I agree about the color scheme and background image. Also in the top banner try to avoid using Times New Roman as a font, its too simple and boring to me.
Have a look at Woothemes, they have plenty of free Wordpress themes that look great. I agree with previous posters about the background being really distracting.
Doesn't look very prof. and this background and pictures are very disturbing and annoying. Content organize wise okay. Also you don't have SEO, Add meta tags and write a description.
Good idea and great work. But something Wrong in your site. Your is PR 3 but Your Alexa 8690734! That is not rally good at all! Your theme is WordPress 2011. You background is not charming to me!
I would recommend you to use more titles for your different paragraphs with keywords in it, and to put your keywords in your articles in bold. That always helps for my SEO and it makes reading the articles more pleasant.
I like the idea behind the website. But you need to change the template, background is too simple. The information and posts are great.
