Thanks!

> You can do this with the `wpdc_change_post_category` filter. It’d be something like (untested example code, but may work out of the box):

I believe you mean `wpdc_publish_post_category`? `wpdc_change_post_category` doesn’t appear to actually exist. It’s just a custom function name that can be anything, correct?

`$wp_category_name = get_the_category( $post_id )[0]->name` is missing the closing `;`.

After that, I get a **too few arguments** error concerning `function wpdc_change_post_category( $category, $post_id ) {`. It might be because `$category` is undefined? I may test more later.

Concerning adding this as an official feature, I don’t think it would be that big of a can of worms, considering two options:

1. The **Force Category Update** option already exists. This could be extended to a feature that forces Discourse/WordPress categories to always be in sync.

or

1. Maybe they don’t need to be in sync at all, but rather if a category doesn’t exist in Discourse, it simply creates it.
