Forum How to make the Username bigger in thread-posts only?
 

In my forums, I tried making the usernames bigger.
But as I make it bigger. The Currently Active Users becomes bigger in size as well.
Even in the Top Statistic usernames.

What I want is the username will get bigger only in the thread posts they made.

^ this is my forum and the names are so small in size. :(

How to change this? :)
