I searched this but seem XF didn't have an option to enable this function (users viewing forums) in admin page.
Here's my forum having this http://www.webmastersun.com while another forum http://www.internetmarketingstar.com , base on XF, I couldn't show/have like that.
This mod is rather important with me, it helps me monitor users viewing on forums
Are there any ways to know users viewing forums for my forum?
Thanks in advance
