This is the forum:
Webmaster, meaning helping you to create a better website, or forum. You can advertise your forums or websites here, and you can request reviews (where they tell you the ups and downs of your forum). They simply move the reviews to the Completed section when they are done with the review.
It's basically a place where a bunch of admins or staff, or just members can come together and discuss forums, websites, and if they want, have small talk.
