sorry about the cookie issues earlier. We had to switch to .stackoverflow.com style cookies (note leading period) for chat to have access to the domain's cookie for auth
so, some people still had the old cookie, which we honor..
how long will it still show people in the list if they haven't used the 'leave', but they close the tab? For example warner hasn't spoken in several hours, but is still in the list. Does that mean he is here, but idle, or gone and didn't know to click leave.
