I wholeheartedly agree with benjad, I'd like to see more emphasis on your content. I like the news section, but I'd like to see your information taking center stage. It is better than the old site, although I like the tabs you had in the old one better than your current nav system. Also, to enhance usability, you may want to incorporate a search engine.
As far as design goes, the colors are nice with the light grey and dark blue with the redish orange accent color. I'd like to see tat developed a little bit more, throw more color around. I'd also like to see more of a difference between the headline text and the body text. Right now, both are about the same size, just the headline is bold. Maybe change the color of the headline font and make it bigger?
In addition, it may be more effective to have your blog and your forum share more of the same formatting and have your logo on them. Right now, it seems that they are not a part of your site.
All in all, I think you have a terrific site so far. I love that you used CSS to produce it and when the site gets going, it will be great.
nice and clean design. I also like the contents. The only problem that I see is that the visitor doesn't get the idia of what is this site about before actually reading the text. You might want to change the "atmosphere" (or look'n'feel if you like) of the opening page, to better reflect the fact that the site is related to IT/computers/etc.
Plus: the Guides section is actually DIY Guides, thus a change in the section title is a good idea.
And finaly, the forum: it's look is very different from the look of the rest of the site. This gave me the impression that I left your site and switched to completely different one. You defenetely need to work on homogenizing the look of the different parts of the site.
You must do something with the font. Make the style of the font in the CSS. Your font is a bit too big.
I updated the forum so it looks a little more similiar to the rest of the site.
Got rid of the News link at the top, and trying to get a viable two column setup for the News in Brief section, but not working so great in css... anyway.
