The dot is green if the user has been active on the site less than some amount of minutes ago. I think it's supposed to be 5 minutes, but I'm not sure. Red means they haven't (mostly because they're offline). SO basically what Healmeal said.
well this has been answered and may be locked.

It's true, but no need to say it for the mods... That's just pointless. A thread that has been answered can be reported to a mod for locking, but stating in the thread that it is available for locking is plain pointless.
