Not sure what you mean but I think you might want to look at this in your config.php:
Text Formatted Code
// Define default permissions for new objects created from the Admin panels.
// Permissions are perm_owner, perm_group, perm_members, perm_anon (in that
// order). Possible values:
// 3 = read + write permissions (perm_owner and perm_group only)
// 2 = read-only
// 0 = neither read nor write permissions
// (a value of 1, ie. write-only, does not make sense and is not allowed)
$_CONF['default_permissions_block'] = array (3, 2, 2, 2);
$_CONF['default_permissions_story'] = array (3, 2, 2, 2);
$_CONF['default_permissions_topic'] = array (3, 2, 2, 2);
