Just wondering, does this forum support lurking mode, where other people can't see what you're doing?
Partially.
If you're in a part of the forum that other people don't have access to (forum staff secret sections, War team secret sections, PvP Event team secret sections, Brawl team secret sections, etc.), then they get a "Nothing, or nothing you can see..." when they check the Who's Online page.
Otherwise, you could just log out and view the forums as a Guest.
