sorry to all, I got little troubles with my pc. Now everything is ok. Here is the link http://www.articles.doknow.org
I like the design. It's nice and crisp. I disagree with the post saying it is too light. Make sure you replace the default favicon.ico. At the moment you just have the Joomla one. The slogan "Free articles for what you need" is clumsy. Your whole aim is to convince people that these articles will be well written, so if you can't even write a good slogan, it doesn't really inspire confidence.
It's easy to navigate, but to be honest I too think that the colors are to light and the Joomla fav icon does look a bit odd, if I were you I would get my own. My question to ask would be, why would I want to read the articles on your site. There are many around where I can read them too. I would add a little paragraph to the main page, or put a describing slogan on the site.
really helpful, a nice job. looks as though a lot of work went into this. really wonderful and very helpful
