Jason, they use vBulletin4 here. Blogs are baked-in to the software.
I feel a piece of feedback coming on. Chancey, I’m coming to get you!
EDIT: Here we go: https://forums.unrealengine/showthread.php?29728-Please-introduce-blogs-to-this-forum
There’s no site feedback forum, so went with this, even though it is primarily about UE4 feedback.
I guess it depends on whether they think it will impact other forums, or building the new section will be a hassle, or they have mod worries, etc.
