You´re right, that´s pretty deep in the core. Though from a SEO perspective it´s also a nightmare to start a project with URLs you have to rewrite later – Let me know if I can contribute in this special case, the project itsels made huge steps forward – thanks for your work.
I´m running a wordpress/buddypess/bbpress combination and I also need to change the permalink structure, in a bit different way then eleram – I´m looking for a more logic structure in all forums: example.com/forum/name-of-forum/name-of-post/
-> replace slug “forum” by name of forum
-> replace “topic” by name of topic
I can customize the code, but I´m not sure where to look on.
@John: “WordPress handles the rewrite rules for bbPress’s content types” -> where do I have to look for (bbpress´ custom post types) to adjust the permalink logic?
Of course I will share my customization as soon a sfinished.
