When I try to post, it won't let me post in most categories. A list of the main categories appears in my drop-down menu, but when I select "Other Topic..." it's a dead-end. It doesn't open up more categories and if I type in the name of a category (existing or new), then the "Post" button will not work. Am I missing something, am I using a shitty browser (FireFox), or is this something that needs to be fixed? Thanks.
