Whilst I like the quickness of loading the new skin offers, as well as the more polished feel, its narrow with and dark colouring put me off it. I feel like spending too much time on it will give me eye strain -- and its rather bland, there's no real diversity in the colour scheme. Maybe look at FM's dark skin for a possible palate?. Obviously lost features etc aren't to do with the skin, but the update so I won't mention them. However, I think it's a bit too blocky, and the numbers for pages of the threads look awful -- far too attention grabbing and distracting. I also miss being bale to see the info page about the user down the right with who they support / where they're from, since this gave you a bit of b/g info on who you're talking to, whereas now they're just a name on a page...
Overall, I think the old skin was better, and this will require a lot of tweaking before people will warm to it. Also, I'm disappointed there's no skin choice -- FM itself has a light and dark version after all!
Finally, I appreciate how much of a pain in the *** making and fitting new skins is, and I'm not disputing that a lot of effort was put in -- that it is (seemingly) bug free shows that the admin and mod team have done a top job.
