I am not sure what the consensus is on navigation but here is my opinion. When reading a thread I start at the top and read down to the bottom. At the bottom there is no easy way to get back to the forum I started in; there is a navigation button but if I am in "General Woodworking" I have to click on the bottom right navigation button then move my mouse to where it will scroll down to the forum then click on the forum. THe other option is to click on the "Top" buttom which leaves my mouse at the bottom right then I have to move it to the top left to click on the forum button. It seems like it would be easier, less clicks and faster, if the forum navigation button that is in the top left were also added to the bottom center, or somewhere at the bottom of the page.
