When you made your account, did you went to edit your profile? Anything? You probably pressed something. -Shrugs- You should probably check your "Profile-Account Related Settings" And check your category (Which says "Email") And look down at where it says "Hide email address from public? or Show others your online status?" If you don't have a check a check next to 'Show others your online status.." then check that..And you little box would tell you "online" or "offline". So it's not a bug..(I think) Hope this explains.
