Hola y gracias @nickmy !!,
I’ve been working hard on deellas.com, but It’s a work in progress.
1. No plugins are used in this section. What do you mean ? What for ? Just ordinary posts with youtube URL custom fields.
2. It’s a bbpress external installation (out of BuddyPress, firstly we tried to integrate both, but It was a mess, eventually we decided to install them separately)
