XF 1.5 Commenting on posts. Stock or Add-on?

[WRIST.pub]

I'm running a small board and the Xenforo board we migrated from gave members the ability to comment on a post:

Topic: Baseball

New York Yankees Players (thread)

Babe Ruth (post)
Lou Gehrig (post)

Gehrig's farewell speech made me cry! (comment)
Me too! (comment)
​

I've looked through the Admin options and such and I couldn't find anything, so I'm guessing it's an Add-on.

If not, please point me in the direction to turn commenting on. Such a basic feature I figured would be standard.

If an Add-on...any recommendations?

Thanks in advance!

Really? 43 views and not one person knows whether comments are stock or add-on? Huh.

It is not a stock feature and there are a couple addons for it. Here is one such addon: https://xenforo.com/community/resources/th-post-comments.4859/

This one is good:

I didn't end up using it globally though as my members love their signature images ..
