bbPress.org

I have used Stephen’s code above and it works perfectly.

However, I have 8 forums on my site so if I wanted to add a random button for each separate forum that only selects topics from that forum would I have to create 8 different function ntwb_bbpress_random_single_topic() in my .php and include only a single forum ID every time or is there a better way to implement this? Also, how and where would I add the shortcodes so that they only show on the relevant forum?
