UBB.threads PHP Forum Software Community Forums Resources and Customizing How Do I? Make Me Invisible

I have noticed on this forum as well as another ubb.threads forum that in the 'who's online' option there appears to be a user who is invisible. My assumpion is that it is the Admin.

So, how do I make myself invisible? Do I snap my fingers like Burt and believe that no one can see me ? (tvland for you folks who don't know which Burt I am talking about)

Thanks,
