New Forum works pretty well, but I have some issues with the Back Button. It must use methods like many JavaScript libraries do lately of capturing the Back button and History and handling it on its own. It does a poor job of it though and makes it more difficult to get back to pages. Often times it seems to remember scroll positions (Not href targets, but positions on the page scrolled to) and hitting back just jumps all over the page. Or it will just sit there like it has no clue where to go. I usually end up clicking Forums or the thread location in the top history arrows to go where I want because it is faster to just reload the forum than try to go back to the previous page.
