I'm currently looking for a way to show my active users online at the bottom of the forums instead of on the side? This is just the way I'm use to it and would like to have it the same way with xenforo.
You need to associate your forum account with your customer account so you have full access to all the customer forums.
You can do that here: http://xenforo.com/customers/forum-users
The reason why I want it at the bottom is that the board doesn't look so good when you're copying it over to a web layout and especially if the content box isn't that big, I think it was only 760px wide while the footer would fill the entire bottom.
Here's an image example, the empty space next to forum stats is where user's online would be, I don't require "staff online" as I'm more than likely going to use colored names.
I was considering IPB at the time, just found xenforo to be better and eventually surpass it within a year.
