Long time browser, new time signer-upper.
Just a couple things, I really like the overall feel of the new design - great job there, but, I agree with a few previous comments:
A) I think the splitting of each post needs to be worked on. I think even just a faint "border-bottom" would work
B) When I signed up, I had a lil click around on the userCP menus, and on Private Messages I got a warning:
i) "NO_AUTH_SEND_MESSAGE_MIN_POSTS" - I understand that's probably a function telling me I'm not authorised to PM until I've met a certain level of posts
ii) I have 2 "Edit reputation settings" down the left hand side under "Board Preferences"
Again, I love the new update, its a massive improvement
