Is when your viewing a thread also show who else is viewing the same thread, that way if your trying to help someone you know if they are there or not.
I know some forums have this feature (which I love btw). One of the great things about a forum is that the post stays there as long as the forum is up and a mod does not delete it. So if you're going to help them or not, just post. They will see it eventually.
You can also open a new tab and use the online list.
