what do you want to change ? M_LEVEL is the database field it is used to give the forum variable mLev a value, however the values are not he same, an M_LEVEL in the db of 3 would be an mLev in the forum of 4, this is because there is an extra value for mLev which denotes that the user is the author of the post, but this is not stored in the M_LEVEL field of the database
