Re: Single log-in WP, bbPress and Gallery2?
bbPress and WP are easily integrated so that bbPress uses the wp_users table in the database, so what you are trying to accomplish is very easy to do. As for embedding gallery into WP, from personal experience it works fine and permalinks are configurable. I would check https://wordpress.org/support/ for more data on that though, but integrating the 3 should be pretty easy and straight forward! Integration is covered in the “FAQ” link of this forum!
