open on forum - - - not headlines ??

hi
   how do i set it so  our forum opens on the forum page ??  mine does,

  BUT MEMBERS  OPEN ON HEADLINES   not the forum page  even if you  close  from the forum page, it  always opens on headlines for them , i have been around to 4 members house's   to check,

  thats the thing thats putting them all off the forum, its to messy for them,

IF I CAN NOT SET THAT FOR THEM CAN I  DELETE THE HEADLINES PAGE,??
