So I checked my WP forum plugins but I dont really like them, is there any way I can use the Wordpress login to login on MyBB \ phpBB \ vBulletin ?
you cant configure WordPress admin panel with phpbb. It could be possible but it will take lots of time and complex work.
You could get some Plugins and Mods to integrate that into your site, it takes a few hours to get it right but it sure is worth it. Poke around vBulletin.org and Wordpress Plugin site, they have some great topics.
