I don't know if this holds true for any other browser, but the drop down menus attached to the navigation links do not work in Google Chrome. So if anyone else uses this browser (as I now do, and love it, but it makes life on AF hard!), you may have troubles accessing certain areas or performing certain functions on the sites.
Most things can be reached via multiple routes, or clever use of links from one section to another. However, some things you simply can't do, period. For instance, you cannot access the blog drop down menu when using Google Chrome, and unfortunately, there is no other type of link or option in those pages which allow to create new entries.
Some other things are different, like with the interface for threads and creating posts... took me forever to figure out how to manage threads and such without drop down menus. x_x
Anyway, if anyone finds any more problems with using the sites with any other browser, or more with Google Chrome, please feel free to list them. I'm not currently sure if it's something that can be fixed to adapt to it on our end or if another browser is simply the answer.
