article system used here.
 

How is the articles system setup here?

Is it a mod or is it just a regular forum?

thanks!

it's a regular forum, with template edits and maybe a little addon or two, but basically, it's a template edit.

It is just a regular forum with a different postbit for the first post in the thread.

Also I think there are different permissions so that articles can be reviewed by the staff and then approved. Although im not 100% on this.

That is just standard vbulletin usergroup permissions applied to a single forum. It's a forum where users can see their own threads, but not those of other users (Can View Others' Threads > No).

thanks for the info, appreciate it...

How can I make it use a different postbit on the first post in just one particular section?

You would have to write a plugin to do that. There is a mod called Chief First Post that may do that, I'm not sure. Or do a search and see if there are other modifications that will do that.
