I've seen the main topic page, where you can burrow in and see what's there through constantly clicking down into the sub-categories. I've also found the search function, when you create a page, which lists all of the options for placing your article.
What I'm looking for is a simple list page, where you can glance down and see every category and sub-category on Wizzley. Doing that often provides inspiration, because you see a header and think 'oh! I know a good subject to add to that one!'
Does such a thing exist?
