I now use the outstanding Simple Forum. With WP-Super-Cache installed, however, a side effect is that when new topics or comments are posted to SF, the cache isn’t cleared so that those new topics or comments will show up. Instead, they have to wait until the cache is cleared automatically. Is there a way to make SF clear the cache when new topics and comments are posted? Some hook or something that I can add to its URLs that will call WP-Super-Cache and make it do that?
