To see if everyone else can see it, log out. And, if you need to be logged in to view the forum, the create a new account and don't make them an admin, but leave them as a registered user. You should do that anyway so you can always see what your site looks like from as an end-user.
I think the column you are talking about is just the setting in vboptions to show the moderator column though (Forum Listing Display Options).
