I'd like to know this too. I'm trying to bridge my website login with the forum login so that users don't have to login twice. I want all sign-ins to happen via the website. I'm also trying to connect the hero's assemble app (a member directory/profile app) to the profile feature in the forum, so that when someone clicks on a profile in the forum, it takes them to the hero's assemble app profile). Would love some feedback on this.
