well seeing as the read only is controlled in the w3t_Boards table in the Bo_Read_Perm which contains a listing of every group that has read permission for that particular category.. and some of us have more then the basic 4 user groups really no generic sql query can handle changing it.. not even a replace would work because it could double up the groups and fail... but what ya can do is bring up your phpMyAdmin and look at that table and see which don't have group -4- and ammend that board...
