Might take a while to get used to the changes - definitely looks fresher and more professional. Navigation not immediately intuitive though.
Have had some problems with the New Forum Posts link - as I scroll over it, the list of new posts pops up to the left. But when I move cursor to the post I want to look at, the pop up box disappears. Happened about 10 times in a row for me. Very frustrating. Definitely think forums/new posts should be a bit easier to access. Also, think that the Articles (eg, The Stick Man / Dental Care) should not be so prominent (ie, forums shouldn't be below them). I think more people are interested in the forums than the articles.
I guess Classifieds aren't up and running yet. I tried to post one and get a "you do not have permission for this action" message. But I think it's a great idea to have the Classifieds section - and the subsections within Classifieds seems good (eg, separating baby clothes from strollers etc). Think there needs to be a "post new ad" button within each section of Classifieds - at the moment, it seems you have to return to the top menu bar to find a dropdown bar with "Create classified ad" link.
I'm sure there'll be lots of teething difficulties, but well done for trying the new approach and for the improvements that have already appeared.
