Reply To: bbpress/wordpress/budypress – participants cannot edit own posts
Firstlt, you can change a users role via the WordPress User screen, just scroll down towards the bottom of the page or you can change them in ‘bulk’ via the standard WordPress Users panel.
As to why your users can’t edit their own posts is most likely a conflict with either a plugin or your theme, try switching to the Twenty Fourteen theme and see if it works, if not start deactivating your plugins one by one until a user with the participant role can edit their own topic/reply and you’ll have found the plugin causing the conflict.
