Steam login should be basically working universally now for the site article comments and the integrated forums (option 2 in forums menu). Next step is trying to style the login widget thing, and maybe tweak some of the settings.

Update 01/14/14:

Removed all other versions of the forum over the weekend, and decided on the one we will use. Got steam login/registration working for that. Got the forum embedded into the site, working on making that more seamlessly integrated.
