Howdy! Just a quick question, as I seem unable to figure out the answer for myself.

On each person's profile page (assuming they're online), it says what they're doing. However, what if they are browsing the forum with more than one tab?

For example, let's say I'm viewing my private messages and the misc stuff forum, each in different tabs. How does the profile page determine what to put for the "What I'm doing" thing?
