I have no idea what you are asking for.

He's saying that he wants it to appear as if an Admin or a Mod is online all the time, I assume it's so that his/her users behave themselves lol

that's correct :)

Try to ask it at the support forums. You might have more takers if you posted it at the right place.

Just manually edit the forumhome template to include his username and a comma before the whosonline variable, and then add a conditional to the profile to show the user_online.gif always for him.

I dont understand what you mean :D

Wouldn't the username display twice if they really were signed on? Might make it easily noticeable that it's a fake.

no problem about this ...
but how i can do it ?

OK, the page you're talking about is called FORUM HOME, so go to Styles & Templates -> Style Manager -> Edit Templates for your style(s)... Now go to the Forum Home template... On this page find:
That is the code that displays the online users, so replace it with the following:
Replace YOURDOMAIN.COM obviously with your domain name.
Replace USERID with the user id number of whatever username you are using.
Replace Phantom User with the username

This is for 3.8, may be similar for other versions.
