(Hey, I did this, it can't be that tough!)
Just trying to find the main community forum was a challenge. Navigation is indeed an issue and it must not be. One thing to watch is the number of views for each post and the number and timing of new subject posts. Views are critical as that reflects the casual viewers (who were in the past the majority of people who made up the readership). The number of new posts reflects the number of casual forum participants who felt comfortable participating in the general discussion. Obviously those with a product to sell (say, just to pick a topic at random, workshops!) will labor away until they get it figured out. But even they (those who have no direct relationship to the site) will eventually find more productive outlets if the number of casual viewers remains at a noteably low level.
Oddly enough, it may be the people who are regular participants on sites not always recommended by this site's administrators who may find this new layout easier to negotiate.
