Well i can't click on any of the buttons up the top of the screen (New Topic, Profile, My Forums etc), the default colours are sickening, there are no custom titles for those people who deserved it, all members are now "Senior Members", all email addresses have REMOVE somewhere in them, links in signatures are broken, there is a "baby puke yellow" bar between each post, the post icons (PM, Online status etc) now takes up another 30 pixels for each post in the thread (whereas before they were "floating" within the message text, there's no Navigation drop-down box at the bottom of the screen, quoting/indentation doesn't work consistently for every post, popups for login/posting/quoting, the reply boxes change colours when you click in/out of them
Just a couple of things i've noticed from looking at it for the past 10 minutes.
