Overall, I like the look. Pleasing color combination and a good overall layout. It looks like a professionally-run site that I could trust for reliable information.
A few comments before I have to dash outta here:
I've seen some eyetracking studies that seem to indicate the space at the upper left of the page body (below the masthead) is probably the most important area in terms of being viewed the most frequently. On the home page, this area is occupied by the block explaining what the page is about.
I'm not sure that should be the most important thing on the page. As a small business person, I'd probably be most interested in the forum, so maybe swap that block with the "welcome to our home page" block -- put the welcome block in the middle? That gives the forum and the directory the same background color for their blocks, and since they're both pointers to interior sections of the site, while the "this is what we're about" block is not, it actually makes sense from a design standpoint as well.
I'm a sucker for symmetry, can you tell?
Dunno what it was like before, but there still seem to be a lot of choices on the page -- a forum, a directory, a "reviews" section, and "articles" section, a "news" section, and direct links to 30 articles and reviews. It's still a little hard for me to decide what to do/read first. Maybe cut the articles/reviews/news lists down to the three or five most recent, and make it more obvious that there's more -- perhaps add "browse all articles", "browse all reviews", and "browse all news" links at the bottom of the sections as well as the "breadcrumb" style links at the top.
Speaking of the breadcrumb links, I found it a little confusing, because it's not necessarily obvious right away (unless you obsessively check the status bar before you click any link the way I do) that it really is breadcrumb-style navigation, and the first bit "Platinex >" is actually a link back to the home page; only the second bit links to the detail page. As a user-in-a-hurry, I'd be a little disconcerted to click on what I thought was a link to detail information and have it simply reload the page I'm already on, simply because I positioned the cursor over the first word in the link instead of the second.
Gotta run to a meeting... hope these few thoughts were helpful.
