Re: Do we know where our members are?
bb_location is not called by default but still is typically used on every page. It’s easier to track the request_uri and store it with the title (formal name) of the page since bb_location does not track all pages (ie. edit and topic pages are the same, all views are the same, etc). My User Track plugin does this but it’s not available to the public yet.
bbPress does not use sessions by default (because they slow the system). But there is no need to use them, you can assume after 30 minutes since the last page load the user has left the site. Most tracking plugins work like that.
