Okay, it seems I've found what I'm looking for within class_postbit.

a couple more questions: What is the session, cookie, or variable that say a user is logged in? How can I tell what primary usergroup a user is in (via a variable)?

Note: I am referring to already-present Global variables. If none exists for say, the usergroup, I assume I will need to make a query for it on each page.
