Inactive Super Fund

I also have received this email.  I have no employees under Sunsuper they are all showing to Australian Retirement Trust, however I do have employees showing under Q Super.  I'm a little confused as the Q Super fund setup in MYOB has the name Q Super and the ABN, USI are the new number provided since the merge.  Do we still use the Q Super fund for Q Super employees or are they suppose to be put under Australian Retirement Trust.  It would be handy if there was a more detailed explanation on how to fix this and also agree there should be a list of employees that are affected by this.
