I haven't seen anyone did this,unless I missed it or something.Anyways,It kinda bugs me that when you go though the thread.You see the people have posted but you can't tell if their online or not.Beside of checking the user page or add them as a friend,you can't tell if their online or not.There should be a system where you see the avatar,somewhere where there is a Joined,Threads,and Post;There should be something that said the user is online.This is just my opinion really,I'm not sure if some people would agree to this or not.

Here a picture,hoping that it might make my point or something.If you can't make out because it a bit blurry.What it said in the white box is"There should be something that shows if the user is on or not somewhere in the avatar section with the Joined,Threads,and Posts."

It could be pretty interesting indeed, especially for
exchange with a specific User through thread~ owo
But I just check the User's Profile for now~ :3
