MyBB Community Forums

You know how vB has a module or something that shows how many people are viewing this or that forum:

General Chat (15 Viewing)

Is this module being developed? Is it a good idea?

This forum has it, but I couldn't find it...

I think that it works by default if there are multiple users browsing a forum.

It says it inside the forum, but outside it when viewing a lot of forums, it won't say it, like it does on THIS forum or with vB or other forum software.

It's just not turned on by default.
