What is this style

What is this bulletin board's style? i.e. What style do I use if I want my bulletin board to look like vBulletin.org ?

Not sure what it's called but according to the link on the bottom of each page, it was made by this gentleman here. Hope this helps.

It's a custom one I don't see you getting it to download but if you are good enough you could make it yourself
