This add-on plugin for bbPress is extremely simple and does one thing: parses short codes placed in topic and reply content.
By default bbPress does not render short codes placed into forum posts; this enables short codes. That’s it.
Note: by default, only users with the ability to publish bbPress forums will have their short codes parsed. This can be changed by passing a different capability via the pw_bbp_parse_shortcodes_cap filter.
