Question About Xenforo Article Style Threads

[XFFA.IR Bot]

I mentioned in my pre-sales thread that I am buying Xenforo for blogging and building a community as well. I thought Resource Manager adds article style thread option to Xenforo.

After using a clean install of Xenforo, I realized that Xenforo supports article-style threads out of the box. What's the purpose of Resource Manager then? Do I really need it?
